I think a lot of folk
are missing the point of thin client. I've just installed 50 into a teaching area. Mostly they'll be used for office and presentation work not high-end computing. Space saving is enormous and there are far less maintenance and troubleshooting issues. My ISS department does all the management remotely.
I'm not much convinced by these Wyse jobs though. I looked at these among others and went for JackPCs.

These fit into the same size space as a 13 amp socket. In fact I've got 6 fitted into short vertical power poles on each of 8 island benches. As for power, they pull about 5 watts max which does kind of put the 13 watts for the Wyse numbers to shame, and they get their power over the ethernet.
Not saying these are perfect or even the best, but they seem to be doing everything I wanted and they certainly look cool. Most folk look and ask where the PCs are.
