I have been off and on drooling over the Timbuk2 messenger bags for a few months now and am pretty close to getting one. I currently have a (less than year old) Swiss Gear backpack that is great; however, after I got that backpack, I got my 13" MacBook Pro (Mid-2009) and started to get into the "Mac" style. I'd use it mostly for school, but also would like to use it for general purpose of going around town too. The messenger style with its ease of access to the insides is what has really compelled me to look at one even though I have a great backpack. It seems to suggest a more "pick up and go" lifestyle which would be great for school and perhaps get me to bring my MacBook Pro and stuff elsewhere too. Which one would you recommend? The Timbuk2 D-Lux Race Stripe Laptop Messenger Bag (Medium, Black/Gunmetal/Rev Red), or the Timbuk2 Command Laptop Messenger Bag (Medium, Black)? Thanks for your advice!
