In the experimental section of the Amazon Kindle is a web browser.
My wife let me look at one they use at work.
Last night, I was able to login and view my miles and reservations with seat assignments. Since this is in the "experimental" section, I wouldn't yet rely on it, but it certainly would make me give special consideration to buying one. Unfortunaley, I had trouble logging into gmail, but yahoo worked.
I am curious to see if Kindle can handle the AA BP...
I suspect that if they started to be used for a lot of web activity, the wireless access would no longer be free.
