I really couldn't care less about the boot up animation. Whenever I power up my devices that take more than 10 seconds (which is basically all of them except for my gaming consoles) I turn them on, do something else for a little bit, then come back when I know it is fully up. I don't turn my Xoom on and off often. I treat it like my phone and turn it on when I wake up and turn it off when I go to bed. I don't see a need to keep devices on that are getting absolutely no use (although I often keep my computer on throughout the night..)
