> 2.) The Surface RT is slightly heaving than the latest generate iPad... The Surface Pro is supposed to be 2 lbs.,
I had the Surface RT (with touch keyboard) in one hand and my MacBook Air in the other hand. The MacBook Air felt lighter. I did the same thing with a Surface Pro I wasn't supposed to see on a different occasion; the MacBook Air still felt lighter. It could be the Surface Pro I saw was a hardware prototype.
Weight doesn't seem like the Surface's major advantage.
> 3) There is no start button in Windows 8 or Windows RT
You're right that there isn't a start menu in desktop mode (unless someone installs the popular apps that put it back). However, there is a hardware start button on the surface RT I saw... and I did hit it quite often when holding it in landscape. Somehow my hand just wanted to hold the device in the middle from below (perhaps because it's easier to balance? Torsion is heavy?) and got tired much quicker when holding on one side.
The desktop looks like this: http://oyster.ignimgs.com/wordpress/stg.ign.com/2012/11/Surf...
2.) There are two Surface models, one is the Surface RT (which this article is talking about) and the other is the yet to be released Surface Pro.
The Surface RT is slightly heaving than the latest generate iPad.
The Surface Pro is supposed to be 2 lbs., which is lighter than the smallest Macbook Air and with the exception of form factor, it is every bit a real computer as is the Macbook Air.
3.) There is no start button in Windows 8 or Windows RT, so I don't know what device you were demo'ing.
