It could be one of the last reasons left to use a desktop or large-screen computer.

This  is a video that shows a research project at Adobe together with
a large technology magazine. Unfortunately, the narration is in Dutch,
but even if you don't understand that language, the interactions with
the UI might give you some idea of when and how multi-user interactions
within the same application may be useful. Sure, this is not the main
use case yet, but also consider developments like the Surface tables
where interaction with multiple users at the same time becomes more and
more a realistic option. If even two years ago we'all did not think
multitouch a critical feature and realize in what world we live now,
then perhaps we should not underestimate the importance of these
developments. How can Qt stay relevant if it only begins development of
features when they are already mainstream elsewhere?
You like Qt?
I am looking for collegues to join me at i-Optics!
