Dude, seriously.
A Macbook already costs $999. Why would you think one with a touch screen would cost less?
An iPod Touch maxes out at $399. Even if this thing was nothing else but an iPod touch with a 10 inch screen, why do you think it would be the same price?
Dude, seriously....
I'm thinking that we will get the first adopter tax and pay about 1k for it. It will have the amazing new whatever it will have that will get us to buy it. That is if you are the first adopter personality type. I am and I always pay the tax but it is worth it for me.
It will drop by 20% after 6m-1yr and probably get a revision. But it will be great and get you things that you didn't know you wanted. That is how apple works.
