I saw this in computing magazine and wantted to share it. so vista does have some good points!
Bockenhurst College is installing the Microsoft Vista operating system to reduce energy consumption and save money.
Machines running Vista will automatically put themselves into sleep mode after an hour of being inactive.
… The system will also be able to ‘wake up’ machines that are asleep and require maintenance during off-peak hours, rather than having to activate the whole network.
