RIght. I'm also not on a road bike, so I'm not leaning over to give a nice back for the messenger back to rest on. And I'm not bothered with the perspiration problem - but that's an individual thing.

I got a timbuk2 backpack from steepandcheap that I *love.* it has a place for my laptop... nice pockets... *almost* as roomy as my 15-year-old LL Bean bag (oops... OMG... 22 years old... it was a masters-degree present...)
