Welcome
I had many problems with an IRiver mp3 player. I ended up taking it back and buying an IPod instead but it was a costly exercise which destroyed a lot of photos I had on my computer and also my usb port. Maybe I just bought a dud because the brand seems popular enough but it left a sour taste in my mouth and I don't intend to give IRiver a second chance even if they switch to making plastic buckets.
Good luck with your e-reader choice. I have a Kindle and love it.
