How many people here have used an iPod Touch? BAM. +0.8mm. So I was looking for a tangible comparison to wrap my head around how incredibly thin iPhone 4 really is, when I decided to look up the dimensions on Apple.com. iPod Touch: 8.5mm iPhone 4: 9.3mm Only 0.8mm thicker. Still thin as crackers. Hopefully not as breakable, but that crazy aluminum glass or whatever that is 30 times stronger than plastic has me intrigued. I think I'm going to keep my iPhone 4 naked, just like my iPhone 1! iPhone 2 and 3 were clothed.
