Plastic opening tools make cracking the Nexus shell like cutting through butter, thanks to its retaining clips around the perimeter of the device.

One millimeter.

That's the difference in thickness between the 9.4 mm glued iPad and the 10.4 mm retaining-clipped Nexus.

That's the difference between being able to open a device and service all of its internals, and not.

That's the negligible difference between extending the life of your device through repair, as opposed to tossing it in a landfill.

And most of all, nobody will complain about that one millimeter difference in day-to-day use, but the user-serviceability it brings will make all the difference when the device breaks.
