Engadget was at Sony's press event at IFA 2009 and saw the upcoming ultraportable VAIO X notebook. This 11.1" laptop has a carbon fiber enclosure, it weighs just a pound and a half and is impressively thin. The prototype features an Intel Atom processor, it runs Windows 7 and promises a battery life that should last a (work) day.
The new X is followup to the rarely seen VAIO X505 that was available in limited markets early in the decade -- only then it wasn't sporting an Atom, 2GB of memory, or a 31Wh battery. According to Sony, the choice of an Atom processor is far from decided and is only on display to run the engineering prototypes here at IFA, so there's still hope for at least CULV internals when this thing ships. Unfortunately, access to the rest of the internal specs were software blocked and Sony was zipped tight on details..
