I bought into this whole e-book concept and bought an RCA ebook reader a couple of years ago. I still haven't found it useful enough for the initial purchase. Content is the biggest problem as well as cost. I could buy a paperback version of the ebook cheaper and I didn't have to pay $300 to see it.

I love the idea of ebook and epaper... but honestly it sounds like a lot of hype that'll take so long to get to market I'll be pumping books directly into my brain through a wireless link from my DIY mac! :-)
