I bought one of these a couple of days ago, and I am really pleased with it. I hope Elonex will sort out the free eBooks issues, but for the time being I have opened the ones that matter to me in Word and resaved them as Word files. I don't think there's anything fancy in the free books that makes this a problem.
I have a hunch that the note-taking facility might only be available with the touch screen version, which costs £199. If anyone proves me wrong I'll be delighted though.
