I'd be reluctant to be an Air just yet as it's still so new.

If you ever use ethernet, remember, there's no port. It may be compact and light but as you mention, it doesn't have as good a spec and costs more. You're paying for style and size, and unless you travel a lot, is it worth it?

weight, build quality, multi touch, backlit kb. build quality on air is even better than mb which is no mean feat.
