Yesterday I had an odd experience with my Playbook. When I got home from work after having it on standby all day with the wifi off, it wouldn't locate any wifi. I turned wifi on, and got the green circle with the message 'detecting networks' or whatever, but didn't go any further. I tried to restart via the onscreen 'power off' icon, and while it brought up the 'shut down' and 'restart' window, it didn't go any further. At this point, I was starting to get worried, but tried to force shut down via the power button, and it worked. The Playbook restarted, detected my wifi, and has worked perfectly since.
Oddly enough, last night my Playbook charged to 100% for the first time ever (previously, it had never gone above 96%).
Probably a coincidence, but I thought it was interesting.
