Welcome, welcome. I'm also a Kindle owner and enjoying it very much. MobileRead is a nice place to hang out with fellow lovers of electronic books.
So -- while you're waiting for the delivery man to bring your Kindle, stock up on some good books. Browse through the MobiPocket books here at MobileRead. Check out the free books at
Feedbooks,
ManyBooks, and
Baen. Both MobileRead and Feedbooks have download guides especially for the Kindle which allows you to download books directly to the Kindle through its Whispernet connection.
