I just got a Tenba Shootout Backpack (Medium):

So far so good! It has has a removeable laptop section and fits a 17 inch MBP.
Down the center (inside) you can fit two bodies and a 70-200. On each side is room for at least 6 more lenses and big side pockets that give quick access into the main compartment.
The tripod system is nice with different setups for different size tripods. The waist belt is nice and padded and is also removeable.
Inside it now, I have a D700, Canon G9, 70-200, 50, 17-35, 24-120, Canon W/A adapter, two diopoters and a bunch of filters, hoods, chargers, a 15" widescreen laptop and Gitzo 2 series tripod.
I like it. True test comes when I take it hiking in Colorado next weekend.
