In the interest of science, I went to Sony's Web site yesterday and priced a fully tricked out 3.06lb 13.1 inch Sony Vaio Z i7 with 512GB(!) ssd, 1920x1080 display, and a bunch of other goodies. Are you ready for the price? It will be $4,499.00! Yikes! Of course, it STILL hasn't shipped. Nevertheless, if I weren't a confirmed Mac nerd who insists on being able to run both OS X and Windows apps on the same computer, the new Vaio Z would be tempting.
