Don't have one but used it in the store. Trackpad is great I think. Feels really amazing considering what they did to it.
Keyboard was very strange compared to what I thought. It is kind of clicky. Almost like.... blackberry keys? They click instead of press.
I can see myself getting used to the keyboard in a week or two. But definitely... Different.
The SoHo store only had 1.1Ghz machines on display.
