Great as a laptop computer bag.  I added a padded sleeve from another bag, and still have room for plenty of other items.  Main area zips shut. Good internal pockets (one with zipper); external pocket easily fits large cell phone (also zips); other side has double-zippered pocket, which can be used as slide-over sleeve if traveling with wheeled luggage.  Have been using for several months daily as computer bag, and multiple airplane trips as carry-on, and it's holding up very well - no discernible wear on bag or straps.
