Sony unveiled its newest Vaio X 11.1-inch ultraportable notebook at the IFA 2009 event in Berlin, that not only promises to "set the new standard for stamina" (battery life) in its category, but also promises to be visually appealing with its half inch-thick body made of carbon fiber. Thanks to its materials, it weighs just about a pound and a half (around 0.69 kg). The first in the series features an Intel Atom processor (model unknown), 2 GB of memory, and a 31 Wh battery. Sony says that use of the Atom processor isn't final and it's merely to run working prototypes, so it still leaves a window open for Core 2 CULV hardware. The hardware apparently lets the machine go on for a day without hitting the wall [socket]. Other features observed are two USB ports, SD/Memory Stick slot and gigabit Ethernet. The only video-out option looks to be D-Sub at the moment. The Vaio X ultraportable is slated for late October, its retail availability is expected about a week after Windows 7 launches.
