Think Apple's MacBook Air is one overpriced ultraportable? Have a gander at the build sheet for Sony's refreshed VAIO Z. The same machine that we took a peek at this February has seen a predictable fall update, right alongside legions of other Sony lappies. The 13.3-inch machine can now be ordered with a presumably lap-melting Core i5-460M (2.53GHz), Core i5-580M (2.66GHz) or Core i7-640M (2.8GHz), an optional carbon fiber colored casing, up to 8GB of DDR3 RAM, 256GB or 512GB SSD, optional Blu-ray Disc burner, an SDXC card reader and NVIDIA's GeForce GT330M graphics card. Oh, and did we mention that there's a 1920 x 1080 screen resolution on this thing? Maybe that explains the $2,249.99 starting price.
