Doing the math, 5.5" seems like it would fit the 6" width of 257. But, 257 has compartmentalizing dividers in between which probably decrease the width. Does it leave room for a small water bottle and a paper sandwich bag? Do not laugh...being on long rounds requires me to bring a lunch. Anyways, 258 has a 7" width, but is that 7" only of the main compartment or does it also include the extra zipper pocket on the front. I am thinking the main compartment of 257 maynot meet my needs, but maybe the 258 won't make much of a difference. Has anybody come across or taken actual measurements like this on both 257 and 258 (width without the extra pocket). I am not sure how the official dimensions match the pics posted below.
If you're planning on carrying the above everyday, I'd suggest the 258; that sounds tight for the 257. The text/laptop/notes will fit in either, but the 257 won't allow you to carry the bottle/lunch very securely. I oftentimes wish my 257 had an external zippered pocket - in fact, almost enough to want to get the 258.
