I've come to the conclusion that "fast boot" can be counter productive.

SWMBO has a Windows laptop that's quite quick to get to the login screen, but from the disk activity indicator it's clear it's not actually booted - just prioritised getting to that screen. I still haven't trained her to wait the FIVE MINUTES it takes for that disk light to slow a bit before expecting anything to work. As it is, she clicks on an icon and "nothing happens" - or nothing seems to happen until a few minutes later the program actually opens when the system gets the chance to load it from disk.

So which is "worse" ? A system that is "slow to boot", or a system that is fast to boot but "doesn't work" when it apparently is booted.
