I'll join, when I get my next tower. I have gotten into the routine of shutting down my TiBook every night when I am finished, and then just powering it up the next day. I never really have any issue with the time it takes to come up, since I am usually just getting home when I do that, and have to make some dinnah first.
If it wasn't for the heat issue, I would be more inclined to leave it running. Oh yeah, and I only have the screensave go active after 10 minutes of no activity. I found that it is much happier if I don't have the drive spin down, or do any processor speed cycling. Makes the wake from screensaver happen in an instant.
I just hope something gets released incredible at MWNY and I am able to afford buying it. I would love a G5, but would take a GHz+ single processor G4 as well. Top it all off with a Radeon 8500 (either 64MB or 128MB) and I will be rushing to get one. With there being three Apple retail locations under 1-1/2 hours from me, I am fairly certain that I could get one fast enough. 😀
