If Apple maintains their solid hardware design, I think that such a computer would be an awesome addition to their line up. I wouldn't mind buying one, if it's priced right. Here are a few things that would interest me:
1. The Intel processor - there is way too much software that hasn't been successfully compiled on the PPC processor (very frustrating).
2. Wine would work (I would really love to use wine and finally kick my meager dependence on M$).
3. If I had to use Windows, I could and it would be on some of the most elegant hardware around (including the iBooks and iMacs).
Those are just some of the reasons why I would be interested. Of course, I'd like to see what kind of hardware they use. I'm sure it would have 512mb of RAM and at least a 1.5ghz processor. I am more interested in the optical and hard drives that they would include.
