I saw some boxed versions of XP at WalMart the other day too. I thought they were just leftovers from the backroom or something, but I guess it's still for sale.
It'll be interesting to see how much they start going for on eBay.
My wife gave me a Kindle for my birthday, and I really like it. In fact, the more I use it the more I like it. Really a great device, especially with the wireless piece that lets you search for and download new books on demand.
Libby has a very good review of her Kindle that's definitely worth a read if you're thinking about getting one. After Christmas, of course...
