iPad 2 being thinner is definitely an upside but is having a thinner glass an upside? Most would think it’s more vulnerable to break. However, despite being 27% thinner than the original iPad, the new iPad’s glass is as much strong. Not just that, it is more flexible in nature too which is what makes it less vulnerable to break.
This has been proved in a strength test by iFixyouri who ran multiple drop tests on the device
