Two iPhones, 6 apps. We know the iPhone 3G S is supposed to be "on average" 2x faster than the iPhone 3G, but stats are stats and what we're interested in is real-world usage. A few seconds here, a dozen or more there, and all of a sudden they add up to minutes.

In this video we launch apps on each iPhone 3.0 device at the same time, but imagine if every time the iPhone 3G S finished first, we immediately launched the next app. We wouldn't make you sit through that much iPhone 3G lag, but that makes the point.

Also, we put a few webpages into Safari, then launched a heavy app, waited for it to load, then exited and went back to Safari to see how many would still be in memory.

Let's just say, double the RAM makes more than double the difference...
