I've been hooked on ebooks (and on MR!) for a little over a year now. The biggest plus point for me is space-saving - I'd run out of room so couldn't indulge myself and buy books. Now I've overcome that ands can buy new titles and also catch up on all the older pd stuff I've lusted after for years. And of course, I can carry my entire library with me wherever I go. Any my prs505 is *SO* nifty and lovely.
