I had a Sony Daily Edition(?)--the large screen one. While it could display PDFs, it would do horrible things to the formatting. Now I have an Asus Transformer and really love it, especially since the new PDF Reader from Adobe is really pretty good. It's more of a tablet/netbook type thing though, but as an academic at an art school I spend a lot of time looking at PDFs, .docs, and .movs, .swfs and a whole lot of other stuff.

A lot of the books recommended here are really old. Good, but old. How about the "Temeraire" series by Naomi Novik (dragons and the Napoleonic Wars) The Ear, The Eye and The Arm by Nancy Farmer (adventure in future Africa) The House of the Scorpion by Nancy Farmer (clones in future Mexico) The Bartimaus Trilogy by Jonathan Stroud (magicians in an alternate history London. Much better than Potter) Jumper by Steve Gould Wildside by Steve Gould (don't hold the movie against him, the books are high adventure in the vein of Heinlein juveniles, but more up-to-date in the underlying societal assumptions)
