The guy doing this review was only able to get 3.5 - 4 hours out of the battery. http://www.nomobile.ru/reviews/162216.html
Mediocre horizontal screen resolution for a 14" too
1600x900 on 14" is mediocre? Bear in mind that it's exactly the same size/weight as the 13" MacBook Air but has larger display (thanks to a narrower bezel on the sides), higher resolution, and an arguably better keyboard. Shame about the battery life, though. Also, considering they're using a carbon fibre shell, they should have been able to get the weight down to considerably less than that of the Aluminium MacBook Air. Sony got that part right with their own carbon fibre VAIO Z (lighter and with better display than either), but it has worse ergonomics than either the ThinkPad or the Air.
No product out there at the moment that gets everything right. The MacBook Air probably comes closest, although the battery life and TN+ display could both be substantially improved.
Note that the ThinkPad X220/X230 has both a better, IPS, display and can run for 12+ hours using a 9-cell battery whilst still weighing less than a 13" MacBook Pro. However, it's heavier than the newer slimmer notebooks and has lower resolution:
