Thanks for the warm welcome everyone. I'm going crazy as the K2 has yet to be delivered today. UPS' shipping status hasn't been updated any more than simply stating that the order is "in transit." Oh well, no sense in going crazy about something I have no control over.
As far as wanting something with a touch screen, I really wanted something that would allow me to write in the margins, take hand-written notes as I read, etc. The more I thought about it though, the less it became about wanting an e-reader and more about wanting a tablet-type computer. That would completely defeat the whole purpose of having an e-reader for the small form factor.
Well, back to waiting for UPS to show up.
