I think the Vertical bag offers greater functionality over many of the other bags. It's compact design gives me what I want: storage and protection for the expensive stuff and some extra areas to add some other papers/pens/etc. The other SI and basic laptop bags are so big that they are better suited for those that really need a full briefcase in addition to a laptop bag - which just gets too heavy and cumbersome for me. Keep it simple, keep it vertical!

It's smaller than the standard laptop bag but just about takes a 15" powerbook. Great cool design, less well padded than the other one but hey, who doesn't use a sleeve anyway!

Extemely cool.
