So, are your skills (and those of your students) going to be ready for the future? :-)
Linux deployments are expected to TRIPLE in the next 5 years or so!
(e.g. from a 12 billion dollar linux market in 2008, to a 35 billion dollar linux market in 2013...:-))

Why heck, it's expected to grow 21 percent, just this year, 2009, alone! :-)

Fire up that KDE/GNOME/XFCE GUI or cli today! :-)

And all 2,400 educational institutions in Tatarstan are changing completely to linux! (Find it on a map...)
And the better known government of Hungary, is now spending half of its IT budget on Open Source!

The world is changing...:-)
