I use it to lug my laptop and gear to shooting locations. Its invaluable if you have heavy gear. However, I must say that I've been using my Crumpler a lot more cos its not often I need so much equipment.
Workmanship is typical Lowe Pro so nothing to complain about. The only thing I dislike are the bungee cords use to fasten the tripod. They are not as good as those on my old Photo Trekker AW but the Rolling CompuTrekker Plus AW is quite a bit cheaper.
