Suspend (to disk) is valuable in itself, separate from sleep.
Everybody has preferences, but if I put a laptop in a bag, I want it suspended. Everything should be as it was when I left. Not doing whatever wakeups I might be happy with if it's sleeping on my desk.
Also immensely valuable for desktops on UPS. Run for a while, then suspend until power comes back. The UPS battery will not run for very many minutes, even if there is very little load.
