I got the Nexus 7 for my daughter. Screen spontaneously shattered after 3 weeks (hairline cracks to upper left screen despite being kept in rigid case). Having looked online, there seems to be alot of reported incidences, linked to screen overheating or similar flaw.
Think I might have to bite the bullet and replace it with a mini ipad after all.
Because that won't have problems will it?
Why don't you just replace the Nexus 7 with a new one. I can't say I have heard reports of this issue. It's an incredible tablet, especially for the price...
