I think this could be a winner for me. I use the 17" hooked up to the 30" display, but something super small, light, powerful with great battery life would be amazing. (If such a thing is even possible.)
But, no matter how excited I get, I have been burned enough with Rev. A laptops from Apple.)
As a guy who suffered through the first Powerbook 12" heat and build issues and the unforgivable bad MacBook issues, I am not going to be the test subject here. (Especially when so much is new.)
I may not wait until Rev B, but I am not a Day 1 Buyer of Apple portable products anymore.
With all of that said, it wouldn't surprise me if this is a living room device and everyone has it wrong. (Although, I think that is coming in June.)
While we are dreaming, lets add 2 quad Xeons to get an octal and run it at 3.6 GHZ, with a new power source where you just add water to recharge and only 1.7 lb for the weight.
