I think I remember hearing about this, and seem to remember it was a localization thing. Don't quote me on that though.
I'm more interested in your ebookstore credit. No fair, I want one!
Also, you can get all of those classics and more right here on MobileRead. Although I know a few people who want to beat me over the head with a stick when I say I try for the Sony one first (I like big margins).
I hope you love your new 505!!
