That thing better have a great price. The nearly year old Macbook Air absolutely smokes that thing in just about every respect. Also a 32GB SSD and 320GB HD. Most people don't need that much storage. Just put in a 64GB or 128GB SSD and be done with it, while having the option to upgrade to larger sizes.
Anyways Sony already had an Ultrabook the Z-Series. Which is thinner and lighter. It is also much faster, more expandable and quite expensive. They probably made the specs so low to avoid cannabalizing the Z-Series. They can have an i7 2.8Ghz, 7hour battery (14 with thin sheet battery that snaps underneath), 8GB RAM, 2x256GB SSD RAID 0, 4G mobile broadband, 802.11n, Intel Wireless display, 1920x1080 13" display, dock and all sorts of other bells and whistles.
