Thanks for the info guys. Yeah, I fiddled all over the place trying to figure out how to play music and read a book at the same time, and for the life of me couldn't make it happen. But it's good to know that. And yes, I knew about the user replaceable battery, but figured that since 95% of people either won't replace it, or won't know how/care/etc, it wasn't a big deal to report it. The other 5% will figure out how to do it on their own anyways.
Oh, and RobertB, I try to be as in depth and detailed as I can on my reviews. The readers want and appreciate it, and if they're happy, I'm happy.
BTW, if you have any other ebook readers, mobile devices, or anything else Linux powered you want reviewed in the future, I'm always open to doing more reviews.
