These days, it is nearly impossible to find a computer that doesn't support suspend to ram properly. Do people really shut down their computers so often that this feature would actually be useful? I just don't understand it.
1. Security-- Using whole disk encryption, the machine is well-secured when completely powered off. When on, the key is in RAM and the disk is accessible. This also goes for services that are running.
2. Energy savings-- Why keep a machine using energy, even a few watts, if that adds up to something over the life of the machine?
3. SSD-- My computer boots and halts in about fifteen and five seconds, respectively, only slightly longer than the resume from hibernate.
4. Freshness-- Though rarely an issue, there's nothing like starting with a clean slate each day. No stray processes, memory leaks (FF v4) or conflicts.
