The point of the comparison isn't to compare the two products against each other, but rather to suggest that the Surface is more power/technology for less weight as a portable device.
No, I'm not. I was watching the live feeds - they even put both iPad plus MacBook Air on the scale versus the Surface Pro with the pure intention that one would carry both laptop and tablet on a daily basis, and that they are aiming to have the Surface be a full solution in a single, smaller form factor. Again, it is pretty clear that the intent wasn't to present the weight of product A vs product B, but rather the weight of one solution versus others.
Edit: Otherwise, the comparison is completely redundant - different form factors, different materials, difference screen sizes, etc.
Even the whole theme of the event was that the want the Surface to replace laptops. "You've been told to buy a tablet, but you know you need a laptop. Today we're going to focus on that, and only on that, taking that conflict away."
I would expect a brand new just launched device with the most recent technology available would stack up favorably against an older device that uses a different form factor and has not been significantly updated in about a year.
It's like saying your V-8 Corvette is lighter than your 3 year old V-8 Dodge Challenger. I would be very surprised if it weren't.
I have both the touch and type (mechanical backlit keyboard) covers. The difference in weight between the two is barely noticeable so trust me the way the scale is tipping over, it wouldn't make much of a difference with the substitution. Regardless, a fair comparison would be iPad with its keyboard cover too.
