"You are wording it like you are disagreeing with me, but how so? I said Windows XP was huge and slow and boring. And you answer, "have you read any of the specs, it runs a special edition of XP on an 800 MHz" -- my point exactly."
No I *am* disagreeing. I'm running XP Pro on an Athlon 550 right now and it's fine. 'Special' doesn't mean inferior. Obviously tablets have specific requirements.
"I've read the specs, and they suck. For your $1500-$2000 you get a machine where the batteries last for two hours, and the machine weighs 3-4 pounds."
Tablets aren't designed to compete with notebooks - right now they are portable desktop machines that can operate standalone for limited periods of time. Like most laptops, they can be plugged in and expanded.
"With a responsive enough OS, and a fast enough GUI, the only issues would be streaming video or similar."
People will buy tablets to run their favorite --software -- . Like PDAs, current models will increase in power until the delta disappears. A smaller, faster operating system is not going to change this.
