E-books--Okay already

Did the e-book thing on Overdrive. Checked out "Emma" as that was one of the few titles available. Downloaded the software and voila--a book to read from my computer. If I were going to do e-books, I would definitely get a Nook or something comparable instead of trying to read something from my computer, but at the moment, I can't bring myself to spend $259 plus tax for the reader. I can see its advantages if you travel a lot (which I don't), because the Nook would be easier to pack and use on a plane. Ahhh, technology...it's amazing.
