Don't take this the wrong way, because I certainly don't mean it in an alienating "go somewhere else" way ... but I get the feeling you'd be a perfect consumer for the Moses SmartQ5 and SmartQ7. Plain tablet, runs linux (could probably be made to run KDE). The Q5 is a 5" tablet, and the Q7 is a 7" tablet.

And, to a certain extent, all of the N800 enthusiasts, who care more about "a pocket Linux machine" more than Maemo itself, should at least look at the Q5 ... with the right Linux flavor on it, it might make a good landing place if Nokia really does drop the 4"+ pocketable tablet form factor.

(and, specifically say N800 because it doesn't have a keyboard ... so probably not as happy for the N810 enthusiasts)
