Sony Vaio Z is > 2K, Samsung series 9 has underwhelming specs and costs just as much, Dell doesn't have anything to compete. Lenovo X series is great but really expensive. I hear Asus has something in the works, but it's not here yet. At this point in time, the MB Air is a good deal with the i7. One major fault is lack of USB3, can't make up for that with Thurnderbolt.
I love the Lion OS. The multitouch gestures really give it a fluid experience. This in contrast to my Windows use, which has me doing the same motions and clicking for the last 15 years. I think it's time to evolve as a computer user and move onto something new and interesting!
Also, it's funny how the same folks who were hating Macs, were scolding Windows 10 years ago. Times change, the contrarianists feel the need to stir the pot, and the wise keep to themselves.
