I'm not sure what the engineering reasons for the thin glass is (could be cost or there might be an actual physical/engineering reason). As far as I know the Pearl screens would be near identical in design in terms of having the glass in it. As Pyske said, it would be nice to have a little more structure to protect it since I think a lot of the time it is the twisting that kills it. Unfortunately due to the structure (thin and flat) I doubt it would be very easy to re-enforce it in a way to prevent flexing without making it thicker or smaller. Again I could be wrong, but part of why they may "spontanteously" break is from a pre-existing mico-fracture combined with time/temperature changes etc (the same way a car window with a chip can suddenly crack).
Interesting to see the actual internals of the Kobo though and exactly what the glass screen looks like. Thanks.
