best non-Apple laptop?

When I attend conferences like OOPSLA, I'm a laptop watcher. It's interesting to see what hardware everyone is carrying. This year, I'm noticing the Windows-based laptops. There are a lot of nice-looking designs out there. I keep on noticing, and being jealous of, the ultra-light laptops that I'm seeing. In the midst of this, I see an article over on Cult of Mac saying that Apple's design holding pattern needs to end.

What do you think are the best non-Apple laptops out there? Who do you think is innovating in their hardware design?
