The Vaio X is only lighter when you don't add in the extended battery. Also I don't need 15 hours of battery life. 5-6 is enough for me. I also don't need 3G because I'm a student and I always have WiFi Internet access. Plus the Vaio X can't do any light gaming when I want to and costs a whopping $300 more. The TimelineX 1830T is heavier and thicker and doesn't have a SSD (adding in one would cost $100 if I bought one and installed it myself). Also no good. The 11.6" MBA is more of a just right machine for me.
Anyways just posted to say I finally got the MBA last night and I used it for the first time at school today and so far I'm loving it. Now I just need to install Windows 7 so I can get off the OpenOffice crap.
Haha, you guys are funny rationalizing why the macbook air is right for you. Vaio X, the thinnest, lighest and one of the sexiest laptops. You point out to the fact that the macbook air 11.6 being the better choice because it has a better cpu and gpu, despite it being thicker and heavier. Oddly though, you seem to cannot use the same argument to bump to the next series of Alienware M11x or TimelineX 1830T, both with better cpu and one with better gpu, despite being thicker and heavier.
That note, I am interested in a Macbook Air 11.6 with dual boot to Windows 7 too. Are all the drivers working? What is the battery life like?
