The latest iPad is very thin, one of the reasons to that is it's glass screen which is 27% thinner than the original iPad's. The iPad 2 is even slimmer than the iPhone 4 at just 13.4mm to 8.8mm which is 33% thinner than the original iPad.

Most people would be wondering that the thinner glass would lead it to be weaker but that's not the case. The iPad 2's glass is much stronger and the people at iFixyouri have ran a few tests which prove just that.
