Perhaps this is a discussion that's been had -- but would be interested in hearing ground-level opinions on this, as I've analyzed the specs/photos of each to death.
Intent is to use as a commuter/OTS bag, on sidewalks, subways, the urban jungle (NYC) and maybe even on bike every once in a while --- and one that could double as a versatile casual and 'business' casual bag; nothing too stiff looking is required, esp. in the creative world. (That said, backpacks, or the ones I've used at least, seemed to not do -- and not appropriately fit my age).
Only carry: 13" MBA, a few reads/books, iPhone, pens, etc. Nothing too substantial.
Besides the obvious differences in dimension and the "hefty" feel factor, thoughts on the differences between the two? I've used the ID before and am not a fan, so it's come down to these two, which can both be gripped like a briefcase, carried over the shoulder, etc. (read on another post about using the Pilot with the strap across body option, which is intriguing). Should I wait it out for a "new" bag on the horizon or...?
