I've always preferred to use Linux over Windows.
But, there were some activities that demanded too much effort on Linux or that had no equivalent on it.
One argument that my electronics professors always had is the difficulty on using spice (actually PSpice) on Linux.
Here it is a very nice article on how to use spice in Linux. It also covers nutmeg for graphics.
I must translate that and send the URL to my teachers. They will like seeing that there's one more program they can use in Linux. At least, I hope they will...
It would be much better if our University only used free (as in speech and beer) software... The money could be used for better things, such as improving the labs.
