Hi folks Been looking around for a good work bag and need some recommendations. Typically my bag would contain most importantly a 17" MBP with power cord, mouse etc, some files, notebook, stationary. I work as a architect/designer and am mobile with my work, moving from client meetings and project sites to supervise construction and meeting fabricators etc. I drive so that helps in the getting around places part but I could be standing or having a meeting on job sites carrying my bag the whole time - something comfortable, tough and durable would be ideal. I am currently using a Porter tote but it drives me crazy slinging it on everytime - i'm more used to carrying it on my shoulders, but the handles just don't sit well. As for backpacks - used to have a visvim k20 pack once - loved it but sold it due to its weight. Messengers are just difficult to open if I need to get a notebook or camera out quickly while its on my shoulders. Any of you out here in a similar situation? Would welcome any ideas.... Thanks in advance.
