I'm currrently debating between:

Tumi Alpha Expandable Organizer Laptop Brief (Style #26141)
and

Tumi Alpha Tumi T-Pass™ Expandable Laptop Brief (Style #26145)
I can't really tell the difference b/w the two (other than the T-Pass thing), but more importantly, I just want the "standard Tumi briefcase" that I see most people commuting to work with. I'm sure it's one of these two, but I can't tell exactly. It's such a big purchase. I don't want to screw it up.

Any help, advice, thoughts would be much appreciated.

Thanks.
