I am in the market for a ultrabook and I think I have it narrowed down to these two.
With the UX32 I would not be able to upgrade to a SSD until a later date too.
My budget is around $1200.
Dude it depends what you need it for and what OS you're used to!
I think on this forum you'll find that most people would say the UX32 out of those two choices. I am not a fan of the macbook air I think it is useless with it's inability to be ugraded or fixed and it's locked operating system that allows for very little customization and a much smaller choice of software compared to windows. Although you could buy the Air and put windows on it.
