I just contacted Sony again, because my reader just crashed twice in the course of five minutes, this time reading a book. It has crashed a total of three times since I did the factory restart, and during that period I probably haven't used it more than five or six hours in total. This time it's crashing while reading books, not pdfs. I told them I either wanted a solution or my money back. So I'll see what they say... I'm bummed because in all other respects I'm greatly preferring my Sony to the Kindle
