anyone bought the KINDLE?

I want to buy this, i love reading books and think itl be easier to take pak with me rather than lots of actual books…only thing is..how does it work…does it come with books installed? can i download books from pakistan, even the newly released ones…for eg, i know in pak you dont get all the hardbacks bestsellers like you get here, ive been to their bookshops and they are crap…so will it better for me to the kindle, then download from the net while im there? although itl cost…

hows it work, anyone know..thankss
