Firstly, people, which has laptops and/or netbooks with a broken battery, can use hibernation to keep their current work and restore it at home. Secondly, I sometimes would like to boot into another OS and a suspend-to-ram will not work. Finally, when we are in some place without power supply and the laptop runs out of battery, we can do hibernation to keep our work. For example, my computer automatically hibernates when running of energy. It's also worth in summer that a lot of areas are blacked out for hours because of energy shortage. My laptop can only work for about two or three hours. When I close unnecessary applications and drop the cache, I just have to copy only some hundreds of MB to disk. This process is very fast in both hibernating and resuming the system. I can say that it's much faster than a normal boot. P/s: I'm currently using tuxonice for hibernation D.
