I have long advocated GNU/Linux plus thin clients be the keystone of IT in schools. There are lots of advantages:
- easy, centralized control of all software and hardware,
- easy and quick software updates,
- less money spent on licensing software,
- improved performance because of the superior hardware (storage, memory, CPU and networking) on servers,
- FLOSS licensing, particularly the GPL, makes it easy to respect copyright while having very flexible IT, and
- significant savings on hardware and power consumption.
A bunch of these are mentioned in an article by BC Hydro, but they mostly emphasize reduced power consumption because slowing the growth of electrical energy demand reduced capital outlay for the utility, and preserves the environment. PCs from a few years ago used 100W+ but a modern thin client can run at about 40W.
This is a good news story for FLOSS and education.
