Initially, once I set everything up, I was pretty pleased with my purchase! But after a little over a month (and having really only used it 3 or 4 times in that month), the screen went black but the back-light on the keyboard was still on. So, I figured it just needed to be charged. I left it plugged in for a few hours and then checked on it. Still, lit keys but no screen. So I changed to a different outlet and left it to charge some more. Came back to it, same thing. I tried following their support suggestion of resetting the battery using the tiny button in the back but it made no difference. I never took it out of "S" mode, and never even downloaded any apps or installed any programs. Basically, just checked my email a few times. Now when I plug it in, nothing lights up. The adapter on the charger doesn't have any indicator light to show that it's working, so it could be a faulty power cord.I'm going to attempt to call their customer support line and see if they can provide me any answers. But in any case, a brand new device should last longer than a month.Now my return window has closed so I'm either stuck with a $350 paperweight, or I'll have to search online and buy a new charger and hope that works...
