[color=66ff00]Simple, monitors, no matter how crappy are effectively a long term, non-disposable item. They just keep on working for ages after your 386 becomes a redundant piece of hardware.
Also schools fall prey of advisors who often don't know what the school itself needs.
Schools (over here anyway) know to max out their budget on fewer items, otherwise some muppet in charge of the cash flow thinks 'Oh such and such a department got an awful lot of gear out of their budget last year, they must not need so much money. That's when you get budget cuts.
Ironically, clever spending does not pay off.
