Ultrabook or Mac?

I'll be in the market for a new laptop in the next 2 months & I want to get a high end laptop for college and general use. I want something that's light, long battery life & a decent display. Now the first thing that comes to my mind is the 13" MacBook Air or the 13" rMPB. I'm wondering are there any Ultrabooks that match the Macs because I haven't heard or seen too much about Ultrabooks lately to know myself, the only one that comes to mind is the Surface Pro 2 and it doesn't really interest me all that much. Anyway all feedback will be greatly appreciated!
