I was a little concerned about the "briefcase" armor, I've no desire to see this get too comic-bookish (ala Transformers, super-suit from an ipod), but I'm thinking the previous posting is probably right:  The briefcase suit won't be anywhere near as powerful as the main suit, but it'll do when that is unavailable.

Fantastic trailer, Marvel, Favreau et al!!  So many excellent scenes in that that trailer.. the briefcase, the longer scenes with War Machine and Jim "Rhodey" Rhodes , the Black Widow kicking some a$$, Hammer and Vanko teaming up, Nick Fury & Tony Stark about to make some "Mighty" cool plans to "Avenge" the wrongs committed by fiends like Vanko.....wow. That's the word that comes to mind.....WOW!!!!!

If the oscars had a best cameo actor segment, I would've watched the oscars. That Stan Lee video was hilarious (the gone with the wind cameo was some, stupidly funny $*it.
