That would be it. I just really don't need that much power while I'm out and about. I have four criteria for my ideal laptop:
1. It has very good battery life. I don't like carrying the power cord.
2. It runs Mac OS X, because I'm used to it, all my apps that I use are for it, and its feature set allows me to be more productive than in other systems.
3. It's affordable.
4. It's as small as possible.
This bugger fulfills 1 better than the MacBook, they're on par with 2, when I sell the MacBook I may actually wind up making a little bit, so it trounces on 3, and it also wins by a good margin on 4. I could really care less how thick the thing is; the footprint and amount of room it takes up on a desk is what really matters to me. I actually kinda like a bit of thickness to my notebook (not that I would want this little baby any thicker)
