The comparison chart was created by Samsung, but if you actually look at it, they're pretty well balanced on hardware.

If you take the polished iOS UI and apps into account, you'll see that Apple has nothing to worry about -- yet.

But, the Android competition is clearly catching up. Yesterday I played around with a Galaxy II, and it's a very nice device with a huge screen. Based on my 1-minute consumer impression, the major downside compared to the iPhone is Android, which still isn't as nice and smooth as iOS.
