Yup enjoy the Kindle you surely will love it a lot
Bought mine not too long ago and I'm not disappointed. For now I'm not even thinking in buying other 6", maybe if a Kindle 4 does comes out I'll fall in love with it and won't resist, but only time will tell
And you can install
Duokan an alternative firmware for the kindle, it's pretty good. Better .pdf support and you can read .epub on it but only without DRM I think ^^
Happy reading
