Welcome to MobileRead Abisha.

Glad that you are here.
I've had my Sony Reader for almost two years and have not missed many days when I have not used it. Along the way I have been able to reduce over a full bookcase's worth of paper books as well as several boxes worth of books from the basement. A lot of these were classics that I now have in ebook form. (They are available for free in the MobileRead download section.)
Beyond that, most of the books that I have purchased are from Fictionwise. They are currently having a sale on their 1 year memberships that rebates (through store credit ot "Micropay dollars" the full membership price plus gives you a free ebook up to $10). The thread that describes that is located
here. It ends soon.
Look around, make your self to home. If you need anything, just ask.
