I've got this problem too. I had been using it to browse the internet. I shut it off after almost every use, including turning the wi-fi switch off (but not always). At some point I went to use the internet and I tried to turn on wi-fi (I turned the switch on) it didn't respond. I went to check now and my eDGe seems to be locked up - can't even power off (but that's another matter). I am almost always using the stylus, not my fingers.
