Ultra Slim, Ultra Expensive: Ultrabooks

What is an Ultrabook? It's a cross between a notebook and a MacBook Air and the price is closer to that of the MacBook Air. Seriously. They are made by a number of manufacturers: Toshiba, Samsung, and Lenovo to name a few. I must admit aesthetically they are very appealing. They boast processing speeds comparable to larger PCs with "ultra-fast start-up". I might be tempted... but not at those prices. What do you think? Are they worth the price?
