(I did a search and didn't find anything.) I sometimes 2/3 a week bring my MBP to work. And also at times i take public transportation to work. I wanted to know what everyone uses for messenger bags / back packs. Sleeves / no sleeves. This is my every day carry set up. A simple case for my 15in MBP and my Timbuk2 Especial Medio. It has nice padded sleeve with velcro strap that fits with the case. I have room for my brick i don't really use a mouse. And i can even bring my lunch. What do you use to commute to work?
