I've had once since April 3, bought with the concept that it would be a working tool for when I travel.
I took it traveling and it was my address book, email connection, journal, library, visual display for a lecture, notebook during lectures, photo album, music player and I did watch a movie or two.
I have a word processor and spreadsheet program on it, and use both. And I take typed or handwritten notes on it. I've got a few Hubs on my experiences with it you can check out if you wish.
