They already have a pocketable device on the market: the iPod Touch. That's not what the new tablet is rumored to address. It's going to address the netbook and UMPC type markets. I'd love to see something like this one: MacBook Touch But I doubt it'll happen :-) Otherwise, even just a plain tablet, but one that has video out and USB host ports (so you can connect it to a KVM) would be good enough. As long as it runs desktop OS X, and not iphone os x ... though, desktop OS X with a mobile GUI would be good.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
