I know I can only use 1 reader at a time. If you own 2, what's the reason? If you're thinking of buying another one, why?
I researched like crazy on this board in November 2007 and asked a lot of annoying questions on this message board while I made up my mind. I chose the Sony PRS-505 and my new baby arrived on December 6th, 2007. Even though I love my reader, for some reason I wanted a second one. You guys know how expensive these things are, so I try to justify it by telling myself if 1 need to go for service then I still will have the other one. You know, like a spare car!
So I bought a Kindle. Now I feel like I have the best of 2 worlds and can't imagine not owning both.
