If you are looking for a real good ultrabook, and you need a awesome keyboard than i suggest the thinkpad x1 carbon. I use this baby since approx 1 year now and i am totally happy with it. There was some cpu speedstep issues in the beginning but lenovo has fixed them now. If you don't want jump on the windows bandwagon, it works out of the box perfect with the most linux distros arround, and for sure it works aswell perfect with windows 7.
Give it a try
