Long story short - the touchscreen stopped working on my tablet tonight. Just quit, while I was in the middle of surfing. Resetting, restoring, even a factory wipe didn't help. This is a hardware issue, and from what I can gather, I'm not the only one whose had it.
I'm returning the tablet to Toys-R-Us tomorrow. I don't feel enough confidence in the product to risk an exchange for a new one, that might fritz out on me as well. It's a shame, because I did like it. But not enough to risk a $195 paperweight again.
So, my final weigh in on the Coby Kyros 7022 - if you want a 7 inch Android tablet, I suggest spending more on a better brand. It was easy to root, and functional while it lasted, but I just can't recommend the brand based on my experience.
The tablet was a birthday gift (bought with gift money, anyway), so now my challenge is figuring out what to get instead. I'm not sure I want to try another tablet. My luck with gadgets has been rather poor overall, lately.
Maybe it's time to get a desktop, for a dedicated writing station. We'll see. Funny that this happens so soon after the 3DS price drop.
I don't think I'll have any hassles at Toys-R-Us with a return, since it's defective. Although their return policy is known to suck. If I do have any problems, I'll make sure to post about it here.
