  • The thing about the Apple Watch, to me, is that its success will be only because it is made by Apple. I know many people who say they want an Apple Watch, yet they don't know what it does, what the price is, or why they want it. They don't do research, they simply want it because it's made by Apple. One person I know said they might buy one right after calling it an iWatch, then I said they probably don't even know what it looks like. They said "I saw a picture of it." ONE picture. These are the majority of Apple's customers.
  • Those are not the majority. That's your very limited anecdotal evidence which is no evidence at all.
  • Eh a big minority but I wouldn't say a majority. That's a simple stereotype of Apple consumers, that they are all blind and stuff. While that may be for some, it's not for all. But what support is their for that anyways. Their is always those annoying fans on all sides Posted via the iMore App for Android
  • A part of this is because people trust that if Apple get as far as launching a product, it will actually work and be supported. A lot of companies release devices more as a test it seems, and abandon them shortly thereafter. I know that when I'm using Apple watch if I find a bug that it will get squashed in a software update.
  • "...its success will be only because it is made by Apple..." Is today national-idiotic-statement-day? ;-)
  • So you make generalized, bias, assumptions about people based on what brand of products they buy? wow. Whats next, you should just get it out and start slander and name calling.. I mean really.
  • I don't think it is a majority of Apple's customers, but there are definitely a lot of them, and we should view that as a good thing. I don't want an Apple Watch today, but I can see myself wanting one when there are more things that can talk to it. Companies won't make those connected things until there is a critical mass of watches out there. It is a classic chicken-or-the-egg problem, and in part why Android Wear has not caught fire despite there being some nice products over there. The fact that Apple has fans that trust them enough to buy their stuff early should not be met with derision by the rest of us, but thanks, because those fans make Apple uniquely able to get past that problem. Apple fans' willingness to jump in is what will allow an ecosystem to take root, which eventually help the rest of us get to a more connected world. Sent from the iMore App
  • That is the most ridiculous observations I've ever read. I think it's a neat gizmo but its just not something that really interests me in comparison from the major leap in size of the iPhone 6 Plus which of course I spent a lot of time questioning if it was a worthwhile investment that would last me a long time like my iPhone 5 did. There's going to be the eBay scalpers as well as those on Craigslist. if I'm investing good money into a watch, it won't be one that simply seen a picture of, I'm a "hands on" consumer. I wait to see and feel the weight. I did that with the first iPhone and liked it's browser that put my BlackBerry to shame despite it being a very new and fresh design that eventually changed the entire mobile industry. Not all will agree with me and they have that right to do so. It's a discussion forum after all and I disagree with with your opinion of Apple consumers in general.
  • The reason why is because a lot of Apple customers had issues with products from other companies. For example, my cousin would always get tricked with ads and destroyed his Windows computer with viruses because of it. He got a Mac and never had problems. He also got everything else from Apple and had no problems. So he trusts Apple to make good products. This is the case with a lot of people. My view is that the Apple watch is the most beautiful smart watch out there. Killer design and beautiful display and interface. I crave it. If I was rich, I would get it. But instead I stick with others because they are cheaper, have more sensors, or have a better battery. I also love the designs of other products and have used them. But once again, I have issues with price. Posted via iMore App
  • Apple always has people like that. I don't know what percentage. But it is what it is. I don't really care if they like it or not or if they buy it or not. It's their money. I've read of plenty of people that really don't value a dollar and have always had "enough" money and they often buy shit they don't need and shit without research.
  • Most fanboys watch the keynotes multiple times, most people who like Apple are very well informed.
  • I became an Apple fan since 2011 and since then, I trusted anything that Apple made and will make. But thinking that we're blind, you're very wrong... very very wrong my friend. If I was not overimpressed on their products because they simply work the way they should, I wouldn't stick with them. No one wants to pay premium amount for something where you can buy way cheaper options. I myself is a cheap ass. But when it comes to Apple products,. i know im buying a premium product. And if there's a problem, I know they'll focus on the fix asap. Not so much like their Android competitors.
  • I ended up compiling so many spec lists for Apple Watch I figured I'd put them all together in one place for people who just want to quickly look something up. Enjoy!
  • My iPad 1 was quickly outdated by the iPad 2 which was a huge jump from the 1st to 2nd gen (more than the other jumps--I mean my iPad Air is still fine compared to the Air 2. Whereas my iPad 1 was almost, to me, unusable). I wonder if the same will be the case with the watch? I hope not. Sent from the iMore App
  • It was the same case with the iPhone, and in my opinion, the iPad mini. Apple excels at making second-gen products.
  • I disagree about the mini. All the minis are basically so close to each other that you need strong light and a magnifying glass to tell them apart. To say that the first one was significantly worse or even much different from the rest is poppycock. I bought the second one because I fell for the retina hype, but I had to give away my first one as it was too hard to tell it apart from the second. I didn't buy the third one because other than the hot-glued home button it's identical to the second.
  • 2nd Gen always leaps and bounds ahead of the 1st. Mini is totally the same. The 1st gen had an iPad 2 processor and then jumped to match the iPad Air and gained a retina screen. Sent from the iMore App
  • Sure, but you had a product from the future for a full year before those next generation products arrived. I still have the iPhone 1, iPad 1, and MacBook Air 1 on my studio shelf. They'll always have a special place.
  • My mom has my iPad 1, my Dad has the 2. The three I sold too a friend and I skipped 4 and went straight to the iPad Air. I don't like to wait until the 2nd generation of something I want because I want the joy of using it. It's also great that others can benefit from my early adoption. I think 10-12 people bought iPads because they saw me with them.
  • It happens with ALL tech, phone, watch, tablet and even laptops. Sometimes lag is 1 year vp effort the next, in rare cases it's as little as 6 months (with pissed people)
  • Anyone have an idea of what time on the 10th that pre-orders will start? I'm hoping it's not midnight cause I really don't want to get up at 3 am.
  • It's always midnight, I'm sure it'll stay the same. Sent from the iMore App
  • Midnight everywhere? Or midnight on the West Coast (which is other times in other places)?
  • the pre-orders for the ipad air 2 were at 10am pacific time.
  • Ye, 10am pact if OR midnight Pacific,. The main website is hosted in CA.
  • GBs ?
    2,4,6,8 GB ?? Sent from the iMore App
  • I'm wondering that too.. So far, rumor is 8GB, with 2GB available to music/photos. Rest reserved for, ideally, future app development and OS.
  • That's it! 8 GB, with 2 GB reserved for music, 75 MB reserved for photos.
  • I'm guessing the music is for use with a Bluetooth headset at the gym. Beyond that music on the watch would be useless.
  • Well I hope they change that or it's a setting because I don't really ever intend to put any apps on my watch and 8GB of music sounds a lot better than 2GB. I don't think I've seen or even heard talk of any app that I would want to have actually on the watch. I like the idea of using it just as an extended screen as they described on stage. Remember, *any* iOS app can supposedly send a "glance" to the watch. I can't think of a case yet where I would want more than that.
  • No thanks. Sent from the iMore App
  • There is very little info about the screen itself from the producer. It seems, that Apple Watch is the very first Apple device to use OLED screen, its ppi is much higher than any other smartwatch on the market, also animations are buttery smooth with 60 frames per second.
  • Yup!
  • OLED came out about 10 years ago now. Over time the tech is now stable and staple. OLED is not back lit so you can have curved or roll up screens. Each diod emits it's own light and are "grown" on a surface and use less power. This is a better product for Apple than the retina. It's a good choice for the Apple watch because it's bright daylight visibility is much better.
  • Rene
    Nicely put together.
  • It's a computer - it has a limited life span. That's not a knock on it. Fact of life. Sent from the iMore App
  • Agreed. Tech lofespans are short.
  • After listening to the podcast and reading various articles, I'm convinced to get the sport this time around and see how I end up using it. I'm intrigued by it and definitely see where it can add value to my life, so I want get one especially for Apple Pay, however I'm wary because 1) i've never worn a watch and 2) it's v1. If it's everything I want it to be and more, then v2 I can step up to the one I REALLY want, which is steel with modern buckle. One thing that also bothers me is longevity. We know Apple will leave not-so-old tech in the dust when new features come out. If I spent $749 on a watch I'd want it to last at least 4 years, but I doubt it'll be compatible with whatever phone is out by that point, or in the very least only a partial list of features (like not requiring the phone?) will be available. Another thing is Apple changing the form factor. If I spend, say, $449 on a fancy link bracelet, I want to carry it forward for several iterations of the watch. But how long until the case is so different, these expensive bands won't fit? These are the unanswered questions for which I'm going the least expensive model for now and until we see Apple's upgrade plans/cycle.
  • I agree. I feel as if this time around I should get the Sport as well, but my eyes are set on the stainless steel one because it's more attractive to them lol so there goes any logic, right out the window.
  • The case depth specs do not include the sensor dome. If you open the Apple Store App on a phone or iPad, go to the watch page and click the link to 'Compare Case Sizes', then measure one of the cases to make sure it's actually showing 38 or 42mm. You can then measure the digital crown diameter. I see the crown as just over 7mm (something like 7.1 mm). Then going to, where they show a significant enlargement dead-on from the side, I can compare the crown diameter to the watch depth. The 10.5 mm is the distance from the front of the display to the back of the metal part of the case. The sensor dome sticks out another 1.5-2 mm max (center of watch back).
  • The sensor pack is supposed to kind of dig-down into your wrist though, so the bottom of the steel case would still be flush with your arm (supposedly, I've never worn one myself).
  • Whether it does or not won't keep me from wearing one. Casio says my current watch is 16mm thick, but that's without the extra 1-1/2mm of plastic that sits at the top and bottom of the face to protect the bezel. I'm looking at having a very accurate watch that's 5mm thinner than the one I've had to put up with for 10 years. Of course it would be nice if the Apple Watch didn't cost so much for what is going to be a short life for a watch. But I'm not going to let that stop me now either (I'm just going to buy the cheapest one there is...).
  • Thanks for your insight Dave. I was wondering about that myself. So it's half an inch thick, which is actually thinner than my first impression. Can't wait to try one on.
  • Some folks were concerned with the question of if it was "waterproof". The IPX7 test is pretty darn good, so that means it will be safe based on a test of 1m submersion for 30 minutes. For comparison, I have been wearing a Nike Fuelband for a few years now. It is not "waterproof" according to the specs, but I don't take it off to shower, nor do I take it off when I swim in the pool or the ocean.
  • Thanks to all of you early adopters. You guys can work out many of the kinks. Even though I am interested in the Apple Watch, I'm not willing to get the first generation. Next years' models will be slimmer and more refined. Also, the software should be a lot smoother. If you get a Watch Edition (or any version), remember to take it off during your bath. It will be interesting to see if there will be water damage claims and how Apple will handle them. Sent from the iMore App
  • Smoother software? If you mean native Watch apps, those will take 6 months after developers receive the SDK. All of which will come to this first issue Watch via OS update. Naturally I'm guessing here, but I wouldn't expect the dimensions of the Watch to change for at least two years, like iPhones have. I'm also guessing that Apple aren't planning on iPhone-like product cycles. I wouldn't be surprised if Apple plans a three to four year Watch cycle.
  • It can't be worse than android wear, that has had so many tech review sites give it a lack luster review. The android apps have also fallen under mostly criticism. Apple, for the most part,maw its and tries to do it right rather than rush it. The rising bank account t is testament to their methods.
  • And the Android people are the smartest on earth, seeing the comments here from Android users that Apple users are dumb, just because they can root their devices and they feel that by doing so they are the smartest, what a joke! So guess who is working at Apple, the smartest people!
