I don't think a Linux Desktop is for mass market. In fact, Linux isn't. It's a system from developers for developers. Have you ever tried to administrate a Linuxbox through a http-proxy tunnel? Well, no problems. Even X Forwarding works fine. Try this with a Windows System. You surely will fail. What about different Desktop Environments? Windows only have one. And nativly even without multiple virtual desktops. On Linux there's KDE, Gnome, XFCE, enlightenment, fluxbox, iceWM, ... What about a shell focusing usability? Have you ever used zsh or bash with bash_complition package? The upcoming PowerShell offers great functionality, no doubt. But usability wasn't really a design goal, was it? And, overall, I _trust_ OSS. Install a desktop firewall on your Windows machine, especially one of those old ones, and have a look. There are so many components wanting to connect to some servers in the inet without a need. Sorry, that's not what i want.

with respect, didn't anyone ever told you that there's a xorgconfig binary for this purpose?
