This whole thing happened in a middle school, and the teacher's right, linux is a poor operating system for the average user. Support is a joke, installing is anything but straightforward, drivers are near impossible to find for common printers, and its not developer friendly. How much software can you buy for linux? Some will argue that the best things in life are free, but linux is far from the best.
Support, eh? Let's go into that.
Scanners.
Printers.
Video drivers:
nVidia,
ATI. All other cards are Native, or supported through
X.org.
Multiple monitors? Once again, supported through X.org.
USB is native. Other peripherals are native. the only thing that isn't supported are Windows-based Software modems. iPhones/iPods are even supported under Linux.
Software: MS Office? bah.
Open Office.
Photoshop? heh.
The GIMP.
Audio/Video? Amarok, XMMS, VLC Media Player, Xine, among MANY others.
Communications?
Pidgin, various other ICQ/AIM clients,
Skype.
Browsers? Konquerer. Firefox. Opera. Links. Lynx. Among others.
Mail? Mutt. Elm. Pine. Seamonkey. Thunderbird. Among many others.
Installation? All graphical (save Slackware), and actually can be done remotely and hands-free.
There's a lot of things that Linux supports and does that Windows and OS X does NOT do, so you may want to do a bit more research into what it can and can't do before saying that it is a joke. You'll be surprised.
Also, just because software can be bought, does not mean that it is better.
Actually, far too often her job is to prepare her students to take state mandated tests, and to avoid litigation. The education system is a joke lately.
Agreed.
