This is more or less a repost from Whirlpool but I haven't had much response there as that thread is dying:
I have had a love/hate relationship with this tablet. That is, I loved it when it worked, and I hated it when it didn't. As you can probably guess, I'm back to the hating. Because this is the fourth time this ##!!#%%% thing has broken in a year and a half. I can't really fault Google's customer service (to date) because each time I lodged a request, they quickly issued a replacement. I just wish these damn things would last a bit longer than a few months. It's not like they were cheap either.
Until now, each time it broke it was the same problem: an unresponsive pixel snowstorm across half the screen while the other half continued to work normally. This time though, the power button feels sticky and unresponsive. I can only power up the device by depressing the button for a while. What's more, the device switches to this unresponsive state after a minute or so of non-use. A device reset hasn't resolved the issue. I'm sure this is a hardware issue again.
I probably should've asked for my money back on the third time. Three times is a pattern after all and it was still under warranty then. But I couldn't see where else to go, so hope won over experience. And wisdom. Now I'm out of warranty and I have no faith in the durability of these shoddy things. I know I probably have a good chance of getting a replacement out of Google but do people think I have any chance of getting a refund at this stage?
what does google say?
