Sony claims 6 hours or so without the extended battery, which is almost what Apple claims for the 11" MBA (which is approximately the same weight as the Vaio).
Apple claims 9 hours on the 11".

The battery life thing isn't 100% fair, since it does weigh about a half-pound less than the 13" MBA. Sony claims 6 hours or so without the extended battery, which is almost what Apple claims for the 11" MBA (which is approximately the same weight as the Vaio).
That said, Windows 8 is extremely awkward to use without touching the screen at least some of the time.
I think Apple's 9 hours claim is very conservative. If I keep to 75% screen brightness, be careful not to have too many apps open at one time, I can easily get 10 to 11 hours out of my 11".
