Like many people I'm using Goodreads to keep track of all that. Having entered all the books I've read, and which ones I liked best it gives me good recommendations for other books I might like. And this is working great! My reading volume has gone waaayy up in the past few weeks since I started using Goodreads. True, it's not integrated with an e-reader itself, but I don't mind going back and forth. Another feature I like is that having identified a book I'd like to read, it helps me to find it - including from my Public Library which I've added to the list of sources!
As for the OP's original question, I like the swiss army knife approach of the tablets - give me email, and android's app store, I want it all! If I'm going to have these nice big 7-inch screens they might as well earn their keep. After all, isn't that how Smartphones evolved? Starting off originally as a dedicated phone you carried in your pocket, other functions were added to replace other devices; mp3 players, cameras, etc ...
