We've posted a review of both models at MobileTechReview.com. The review does a great deal of comparison with other ultraportables (Windoze) on the market since our specialty in notebook reviews are the ultraportables and subnotebooks. The MBA does very well in terms of price in the 3lb. and under category 🙂.

I too come from the world of VAIO subnotebooks; I agree that the MBA nails it in places where previous Sonys (and other manufacturers' models) have missed. The VAIO X505 was by far the closest to the ideal subnotebook, with its decently-sized keyboard, eye-friendly screen size/resolution combo, and extreme thinness. I am glad that Apple decided to do their own take on that classic machine instead heading down the more gimmicky, "not-quite-pocketable" design route.
