Tsk tsk! You haven't tried to get games, applications, multiple monitors, dual-booting, file sharing across multiple platforms, ftp-serving, proper permissions for multiple users, or the greatest challenge: Teaching the closest computer-inept relative, to use Linux, now have you?
As for nothing to do, surely there is more to do on that front than Windows. Install, configure, crash, reinstall, reconfigure, recrash, wash, rinse, repeat. :_)
My system runs Unreal Tournament 2003 and Quake servers for me, runs my Gimp app + plugins, and lets me while away my work hours doing tech support for people on online forums.
What is there not to do in Linux? (grin)
