HTC Shift + ThinkPad X300 + MacBook Air = Perfect Notebook?

Tom's Hardware has an interesting look at the HTC Shift, the newest contender in the ultralight portable arena, with a strong compare and contrast to the other two heavyweights, the ThinkPad X300 and the Macbook Air. "As some of you know, I actually like the Macbook Air but found the Lenovo ThinkPad X300 to be a vastly more useful product in the class. I'm one of the few folks that have been using an early version of the HTC Shift , a smaller screened ultra light tablet with a keyboard and a touch screen which is superior to both offerings in some ways and just released on Amazon.com for $1500 (someone screwed up, this wasn't supposed to happen until next week). This got me thinking: The perfect next generation ultra-sexy notebook should be a blend of all three products."

Macbook air is FAR more than 2.5 hours...

I got far more than 2.5 hours out of the air at a conference, running compiles and mysql database work enough that the fan was on 100%.
