> 1) It saves power Shutting down and booting are intensive operations, it's likely that for short enough periods of time, sleep is actually more power-efficient if it works well. I don't have numbers though and with SDDs and fast boot times, maybe booting is way less power hungry than before in the end. Can't argue with 2) of course.
