I'm probably going to be in the market for a new notebook in the next eight months or so, and I think I might end up with one of these once they get the bugs worked out. I'm a college professor, and this seems like it would be fantastic to lug back and forth from the archives and classes, where I use Keynote extensively. I'm a little put off by the lack of optical drive and nonreplaceable battery, but something to keep in mind is that this thing supposedly will get five hours with everything turned on. Turn off wireless and dim the screen a bit, and it could conceivably get much more than that. We'll have to see how it works out in real-world application, but it's definitely got possibilities. I'm still skeptical about the lack of optical drive, but let the early adopters figure that out.
I understand why some people are upset about this, but really, there are plenty of people who would want it.
