I upgraded last night late. The install went well and most of the apps I use regularly worked well. There were 2 I had to clear the data on to get them to work. Amazon app store worked well too. Started it up at 9 this morning and let hibernate even as I am writing this on my laptop. I woke up at several intervals: 9:40, 11:20, 2:00, 3:20, and the last time at 7 PM. The last looked to be a reboot, but no lock ups so far. Opera Mini 6 works, browser crashes, but I have to check the settings for it and I couldn't find it in settings>applications to clear the data. The system is speedier, and more responsive. I like the double tap to magnify the page. I haven't setup e-mail yet. I noticed on the last wake up which appeared to be a reboot, the reader screen bottom third was of a darker shade. I just went to see if a reboot would clear it up, but the wake up call did it for me. I have not used the reader at all today, it has been an errand day for us. Checking the battery status shows 60% left. Not bad, wifi was on, I just closed the covers. I did as Cheyennedonna suggested and left the lcd on when closing it up.
