Mossberg is very impressed with the Lenovo ThinkPad X300, having now used it for a week. I agree that it will be a great portable for the road warrior who needs Windows and lots of ports. As a writer, the Air suits me fine, but there are definitely big markets for both of these machines, and all of this points to the validity of the direction that the Air has taken in laptops by opting for a relatively large display (13.3") and a full size keyboard, all in a package that is roughly 3 lbs. and nice and thin. For those who want to say that the Air is cr@p, and that the Lenovo blows it away, they are just different machines. One will suit some, the other will make others happy. Both are great machines in my opinion. For those who want to suggest again that Mossberg slates the Air and prefers the Lenovo, I refer you to his closing statement... There are two more factors worth mentioning. I believe that both the Mac operating system and the software that comes with it are superior to the Windows operating system and built-in software offered on the ThinkPad. And the Mac isn’t susceptible to the vast majority of viruses and spyware, and doesn’t require third-party security software. Also, the ThinkPad’s screen, when opened, stands significantly higher than the Mac’s, so it is less usable in a coach seat on an airplane when the person in front of you reclines. If you’re happy with Windows, can afford the price tag, and value the many ports and connectivity options Lenovo has packed in, the thin and rugged X300 is a great choice. It’s a notable engineering accomplishment. He is clearly impressed by both offerings, as am I. He doesn't "pit the Air against the Lenovo." Rather he extolls the virtues and describes the limitations of each.
