With Haswell so close (and the alleged huge power savings), this seems like a really stupid time to buy an ultrabook. Wait a couple of weeks and either buy a Haswell equipped model, or a discounted Ivy Bridge one.
Haswell is going to be able to deliver a much better punch in the same power envelope the y series ivy bridge are. The haswell version of all ultrabooks are going to be infinitely superior because of the additional battery life and cool temps. This yoga will get a nice boost from haswell in both the cpu and gpu departments. At 11.6" I would like to see 1600x900 IPS/PLS minimum but it really should be 1920x1080 and the 13.3" one I'd like to see that bumped to 2560x1440 like the toshiba kirabook has but 1920x1080 IPS/PLS is the minimum i would accept on the 13.3". If they can bring the higher resolution with the haswell refresh i just may be in the market for a yoga book.
