Hello Shallowgal -- welcome to MobileRead.
> Hi ~ new member here. what? How unusual is this?
Not too unusual

We have a steady stream of new members and since we nag them until they post at least once -- which doesn't have to be in the "introduce yourself" forum -- we do get a reasonable number of introduction posts.
We're a 5 Kindle family sharing a single Amazon.com account, so you know that I'm a Kindle fan. However, to be fair, I also own a Sony 505 and enjoy it -- though so far the only books I've gotten from the Sony store are the freebies. Since I have been spending a decent amount at Fictionwise and Baen/Webscriptions, I've been collecting multi-format books and thus have plenty available to read on my Sony.
By the way, there are lots of classic (copyright-free) and Creative Commons books available right here at MobileRead. Your Kindle is very happy with the Mobipocket format books which volunteers have uploaded to this site.
