Seriously. That and a portable external screen, and BT keyboard. It's great in that you'd be able to optionally use the N900 as a portable workstation for more serious tasks (document editing/command-line work/coding/picture editing/etc).

Personally, I would prefer carying this setup around to my netbook.

This is a VERY niche application though, so I wouldn't expect official support on this!
