Just found Outdoor Products
They have two computer backpacks I like, one of which I purchased. The larger one is the "Power Pack," and the smaller one (which I picked up at REI for about $65) is the "Power Pack Glide." I could probably fit two decent sized laptops in the Power Pack Glide, but as it is I have a Dell 15" (office-issued, stuck with it, yuck), a MacBook Air 11" and an iPad (original) plus numerous accessories. Still a bit of room left and it's darned comfortable to carry.
Also, thanks to the other posters who mentioned Tom Bihn. While I didn't get a TB computer pack, I'll definitely be getting some overnight stuff from them. Time to replace all the black Tumi stuff I carry.
