This backpack was purchased to replace a Booq backpack that recently experienced zipper failure while on a trip.  I would have bought another Booq, but their designs seemed to have changed in a direction that no longer met my requirements.  This Techtonic Samsonite seems to have been a good alternative.  Great design, although I think it could have used a more substantial, waterproof bottom.  Possibly a little more padding on the bottom, too.
Other than that, it appears this bag was well thought out, and will hopefully last a few years.  Pockets in the right places, soft interiors for MacBook Pro and iPad, as well as pockets for all the support equipment, headphones, books, next-day's clothes, shaving kit, and the obligatory exterior water bottle or two.
It looks good, too, without looking faddish.
