Taking the e-reader plunge

Well, I’ve decided to buy an e-reader.  Shelf-space is what finally pushed me over the edge, to be honest.  As I begin to think about packing (the hubby and I have bought an apartment and will be moving next month!), all I can think of is how horrible it will be to deal with the mountain of books I’ve accumulated.  There’s so many of them, and they’re so heavy.  Have they been breeding and snacking when I wasn’t looking? And where will we put them all in our lovely new place?

Maybe a tiny electronic device that holds thousands of books ain’t such a bad idea after all.

So, which e-reader do you think I should get?  I don’t want to break the bank (I already spend enough money on books as it is) and want something simple and straightforward that provides the best reading experience.  I’m currently leaning towards the new Nook Simple Touch Reader.  But I humbly request your advice in the comments.  What factors are most important to consider and what have your own e-reading experiences been?

Help!
