My boss Bill got himself one of Apple's new MacBook Pro laptops last week. So far he's underwhelmed. Other than the built-in iSight camera, it looks nearly identical to the 15" PowerBook it replaces, and non–Intel-native applications run more slowly than they did on the old machine.
While the 17" iMac I use at work is great, I do miss having a laptop like my wife's 12" iBook for doing work (and play) on the road. The MacBook doesn't appeal to me either, however. It's too similar to its predecessor, and not really the form factor I'd be looking for.
We'll have to see if Apple's iBook replacement (perhaps the MacBook, sans Pro) is interesting whenever it's released.
Not that I could afford one even if it were, of course.
