Iphone 5s is angular and thicker, the iPod touch feels much better in the hand. It is lighter, it is less thick, it costs less, if could also be a phone if only Apple would include the phone software. Your turn.
The fact that you wrote this invalidates every single thing you've written in this entire thread. You're clearly just making stuff up out of thin air, so why bother to debate any of it?
The Touch 5 is indeed the best-ever Apple design. I love my black (or is it slate?) one. Since I don't particularly enjoy yaking on a phone and am at a good wi-fi connection 95% of the time, I don't miss not having an iPhone.
In terms of pure technology per cu in or per gram, the Touch 5 is hard to beat. Rock on!
