I was sure I was not going to like an ereader. I read a LOT. Seriously, first name basis with every librarian in town, know the bookstore folks, etc. I bought the nook, wifi, 3G so I could easily have extra books avaliable when I'm at my dad's or DH's moms (elderly, sometimes situations come up suddenly). I love my nook. It's easy to read, easy to load, updates it's self (we lost internet connection T-Day morning, Dh got us up and running last night, Nook updated it's wifi connection with no hassle, just input the password). The latest Nook software lets me browse the web, so if I am unable to come home, I have something to do, even if I don't want to read.
If you do purchase an ereader, I'd hold off on the accessories. What I thought I wanted for the Nook (cover, etc), I don't want at all a week later. Get familar with the device and then choose the accessories you will use.
