Although late in arriving, Sony appears ready to join the low-cost, ultra-portable, netbook, mini-laptop party. An apparently generic prototype based on the Via OpenBook was just spotted at the Quanta booth at WiMax Expo. It seems that a quick check of the properties revealed a 1.6GHz Via C7-M processor and more interestingly, Sony as the manufacturer. When the Quanta exec demonstrating the box noticed "he quickly closed the properties window and declined to explain." Sony refused to comment. In other words, expect to see it in Q3.
