For example, GNOME doesn't support session save out of box. I think it's an incredibly helpful feature, especially for beginners - but maybe GNOME developers simply know that, deep down, all of us yearn for a clean blank slate whenever we restart our box, and showing the apps we've been using five minutes ago will only confuse our brain.

Also it doesn't even show hibernate button on the "start menu" (or whatever it's called these days) - because apparently the ability to actually power down the box while keeping all states is too confusing to have!
