guys, and girls, thanks for your imput!
I hadn't even thought about the organisation possibilities, but that's a good one, considering I might want to keep my "fun" stuff and "study" stuff separate...
pilotbob: I will look up both those readers and read up on them: I hadn't seen those before because I hadn't looked for the ones that are not available yet.
I just hope they won't introduce them at a too high a price...
A friend and I just made a shopping date for this upcoming Thursday and, amongst other things, we'll hit one or 2 eclectronics stores and I've decided to have a closer look at and testdrive whichever readers they will have for sale instead of just looking at them online.
Including the PRS 600...
btw: what is Sam's Club, is it an online thing too?
