My girlfriend swears by her Crumpler backpack. They have messenger bags as well. They're seriously high-quality, and a good choice if you're looking for something stylish/funky as opposed to the generic office look.
I acutally just ordered a Crumpler bag this morning. I got the "Considerable Embarassment". I ended up with one of those over a Timbuk2 Laptop Messenger because the tb2 bags just looked either a little big for what I needed, or way to small. The ones I was looking were also $40 more than the crumpler bag.
So I ended up with the bag with UPS 2day shipping for $100 even, which is $10 less than the tb2 bag alone.
I've heard only good things about both brands though...

(In the video review, the tech stop reviews the case in the second half.)
*edit* I thought I'd add what he puts the case through...:
Shoots it with a airsoft gun
Runs over with a car
submerges it with water and sprays with a hose
and the laptop inside didn't have a scratch on it and was fully functioning.
