Ok, I do not own a laptop, so I never use suspend. Hibernation/Suspend to Disk is useless anyway because you would read in worst case more data than you would do with a normal boot when you memory is big and used.
That's not 100% accurate, Kano... Suspending to disk takes a snapshot of the system RAM and flushes it to disk, where it resides until you restart. It's "less useful" than saving files out for many instances, but there may be instances where you want it to be just where you left off (There have been instances thereof in my past, I just won't bore anyone with them... ). It's just not useful to you in your past experience. That, my friend, doesn't make it useless to everyone.
