While I wait for my new Unibody 17inch MBP I've busied myself with finding the perfect bag. I need a bag to hold the laptop (and charger), my Seagate FreeAgent Xtreme (and power supply), my wireless mouse, and eventually my slightly bulky headset. So far my choice has come down to the Booq Boa slimcase XL90 vs the WaterField Cargo. Anyone own either of these and is willing to share their experience? My concern with the Booq Slimcase is that it may not be able to hold all the gear. I'm trying to find one at a retail location to size it up but haven't had the chance yet.
