I'd like to see the 'Tom Bihn' take on an A3 portfolio/presentation folder.
I'm sure a lot of TB's customers are working professionals, many of whom have to make presentations of various things to clients.
Standard folders use a D-ring system inside, which holds clear plastic sleeves for artwork/photos etc.
Maybe it could be part of a laptop bag as a powerpoint screen presentation will often accompany the 'physical' presentation.
I realise an awful lot of presentations are just delivered via projector these days so maybe I'm being old fashioned, but I still think this is a useful product :)
