I thought restore from hibernate spent most of its time reading the (potentially multi-gigabyte) memory image from disk. Booting doesn't need to load 500 megabytes of firefox into memory, etc.; is there some reason to think that restoring your individual apps would be faster than restoring the hibernate memory image?

Because -- in theory -- you wouldn't have to restore every application, (don't worry about freezing the memory used by all those useless panel apps). And the apps themselves could be smarter (Firefox wouldn't try to persist its in-memory caches). Crash-only apps could just be terminated and re-launched (IM clients, mail clients, etc), no need to write them all out.
I admit, it's all speculation at this point. :)
