It will replace my Nokia N800. My N800 is the only reason I was able to resist preordering. It's doing everything I need, for now. When the Pandora is a stocking item, I'll be ready to upgrade.
It'll run great if someone ports it. Probably an easy port, too, since it's already ported to maemo. Of course you can't distribute it with the assets. That goes without saying, but the game, itself, is still widely available.
Just FYI, 32GB is the addressing limit of FAT32. Drives larger than that are formating by addressing them as seperate drives, internally, so it can be worked-around. But, that's why SDHC technically has a 32GB ceiling.
Yes, it remembers your pages, on all opened books. There are versions for windows and linux, so give it a try on your PC, if you're curious. It's a very good reader, IMO. It's the app I use the most on my N800.
