Everything said is essentially true. I just bought the Vaio Z (higher end model) for quite a lumpsum, but it's a really solid computer and worth every penny. It has huge battery life (5+ hrs), excellent build quality, tactile keyboard, an incredible screen (1600x900, by far the best resolution on a screen of its class), massive power (2.66 GHz dual core on the one I got), sleek looks, and EXTREMELY light. I like to think of it as a netbook on roids'

. The one major negative of course is the price, but if you have the money to shell out, you won't regret it for a second.
