Samsung has just released a new commercial for their new flagship phone, the Galaxy S4... and it's pretty good. The sheer size of the Galaxy S4 is evident in the ad, as are features like Drama Mode, which lets you capture a series of images -- think multi-exposure sports pics -- and Air Gestures that let you navigate without touching the screen with sticky -- in this case tasty rib covered -- fingers. Some of the other features, like Hover, which feels like a terrible violation of Fitts' law, and S Beam, which is like Bump over NFC, are a tad more gimmicky, and more demo-ware than software, but they come off okay in commercials for just that reason. (Samsung even suggests their screens support smell capture, which was probably a bad idea since injecting farce into an otherwise real, if strange, feature set only creates confusion.)

The iPhone is the best camera you have with you all the time, and that's why fashion photographers and models alike often use it to take and share fun photos while on shoots. Nothing beats a DSLR for final photos, but increasingly the iPhone is the new polaroid for everything else on set. Add in the power and community of Instagram and it really is a whole new world for fashion photography.

To get some industry insider tips on how to take the best possible fashion photography with your iPhone, we enlisted Mobile Nations' own design lead, David Lundblad, the frequent subject of his photo shoots, Amanda Delduca of Capture Fashion, and asked videographer Martin Reisch to document it all.

Ellen DeGeneres has released an iPhone version of a game she likes to play on her show called Heads Up. It's simply a word guessing game where your friends try to get you to say the word on the screen by giving you hints. Only with Heads Up, you hold the phone above your head and it records video of your friend giving hints. You have sixty seconds to guess as many words as you can.

Rumors, as always, are swirling over what next-generation Macs Apple might announce in 2013 in general, and at next month's WWDC show in specific. But which one are you most interested in?

The Retina MacBook Air is probably high on many people's wish lists. Like the Retina iPad mini, getting a 2x display into a device that's just as thin and gets just as good battery life is a daunting task, but if and when Apple can do it, would that be the Mac of your dreams? Or would an updated MacBook Pro, something running Intel's Haswell architecture, be enough, or perhaps even better for you?

What about a Retina iMac? If Apple could ship a 5120x2880 display in that new, razor-edged design, would that be every photographer, videographer, or just plain desktop lover's fantasy made manifest?

The Mac Pro has been languishing in update purgatory for the last few years, so how about -- finally -- an update to Apple's powerhouse? The latest Xeon processors, Thunderbolt support, maybe even a new casing design? Or what about the long-sought after Mac Mini Pro, a tiny tower that's still expandable to some degree but caters to a slightly more mid-range market.

Whether we see it at WWDC, later this fall, or even next year, what's your next dream Mac? Vote in the poll up top and let me know why in the comments below!
