I love laptops which are portable. Why didn't consider the series 9 instead of series 7? However, ultrabooks are usually 12" to 13" range which are a little small if your eyes aren't good enough. 1366 x 768 seems to be a little outdated now as more and more requirement on the 1600 x 900 emerge. Lenovo has just introduced a new X1 Carbon which is very very sexy. I'd love to choose this one if I hadn't bought my R930 yet.
