I wouldn't mind being able to synch with Outlook and my Windows listmaking program. Linux would be nice, too. Don't know much about WebOS but maybe that would be fine. Android is okay with me so far, althought I miss having more than one program/window running at a time.

But whatever operating system goes on the tablet side, I want the e-ink side to retain all of its current functionality, maybe even gain more.

I don't know which answer to choose for your poll. Guess I'd have to go with 4: Have no idea.

Interesting discusion, though!
