me thinks the LCD iMac is durable enough
But schools often just go by looks since there isn't an Apple Store at every corner. The base is really, really heavy of the Flat Panel iMac. You can barely lift it by the base alone. And while the LCD sometimes is not perfectly level because of the hinge not being tight enough when it comes from the factory, the arm is strong enough you could put a 22" LCD and it still wouldn't sag. 95% of the LCD iMac's weight is in the base. If you could imagine trying to knock over a 22 pound book. Closest approximation would be two New York City phone books bound together. The base is bigger than you think. But of course, since you can't tell that from photos, people want a CRT machine.
