Wired has a solid review of the new Macbook. Their conclusion is spot on:
Much like that first Air, the new MacBook is for the future. It’s a vision of our next computer, the one we’ll buy when our Airs or ThinkPads can’t keep up anymore. The MacBook is a work in progress: The processor and the battery will improve, and the price will drop. It won’t take long. The future’s getting here faster than you think.
