A while ago Microsoft released this video to give us an idea of how the UMPC could be used. There's alot about the UMPC lifestyle, but I think they're only scratching the surface on how UMPCs are really going to be used.

When I think Ultra-Mobile I envision doing a few things: watching videos, chatting, web-browsing / blogging, and sharing content with other UMPCs. I'm curious what options are available to share content between different UMPCs.
