We gave my cousin a red PRS-600 on Sunday for her birthday. I had it for a week and loaded a bunch of books to her reader. Made collections for all her books. I loaded about 180 books to her reader and that don't include the Harlequin Present monthly bundles which have 8 books per bundle and I gave her Nov 2008 to Sept 2009. She just called me all frustrated because her reader locked-up in the middle of reading a book. I had her plug it to her computer but it was not recognized. After 10 minutes, I had her hit reset while it was still plug in, and slide the power button 2 quick times and then it came to life. When it came on, she only had 1 bar of power, even though, I fully charged it on Sunday before we gave it to her. She's at Gamestop right now buying a PSP charger. So hopefully that will solve the issue. I'll be sad if it's a recurring problem after thinking we gave her the perfect gift. Now I'm all nervous and thinking I should have given her a Kindle 2!
