Not surprisingly (*at least to me*) is the fact that the number one suggestion on the list is "provide us with PC's that have a Linux distro installed".
There is also an online questionnaire that you can fill in, to provide Dell with some more details on our wishes. I strongly suggest you to do so!
Researching a little further I came across the weblog of Mark Shuttleworth ("the father of Ubuntu"). He also comments on Ideastorm. And then it gets funny... he refers to the bugtracker system for Ubuntu. Their #1 bug has the following title "Microsoft has a majority market share" (and has as nickname "liberation")! The bug is still not resolved..... But I think we are getting there.
Just a thought: would Shuttleworth be a keynote speaker we would like to have in Amsterdam? Just chime in.
