I'm going to jump in on this one in the "been there  done that " position. $50,000 produces approxiately a 1:20 studentcomputer ratio. Add in software and other goodies, maybe a 1:25 ratio. Working back over a three year rolling replacement, let's say a 1:8 ratio.
So far so good  each student gets two hours of computer time a day. But wait: most of my students spend an hour in class and two out of class doing homework. You run into critical time shortages.
Don't forget the cost of human lab monitors. 80 hours a week times two bodies times minimum wage times 32 weeks and there goes your 50,000 dollars.
Startup costs for labs include furniture, networking if you are so inclined, and even rewiring rooms for sufficient electrical outlets. Maybe new air conditioning.
Don't get me wrong: I like computers and use them all the time in class. It is definitely cheaper to buy calculators.

That is all of the students who can afford to spend two extra hours a day on campus, which is not true of many commuting students. Those with computers at home can buy software  those without are out of luck.
Well, this thing sounded negative, but it is a cautionary tale. I want to use both tools every day and want my students to also, but computers are even farther beyond the reach of my students than calculators. Computers are certainly beyond the reach of my school.
