Daniel & Bob
My apple has an option to set sleep mode to never under System Preferences
Once I set time machine to a second drive, I do not see the backup pop up any more.
As far as running software on Mac, there were more that ran on Mac than I expected. I have MS Office, word and excel on mine now.
Bob knowing what you do since its everybody else's hobby here is that to, I imagine you are wanting to put Adobe on the machine. I probably wouldn't go apple if I had to buy a whole new copy of CS5 to put on it. I wouldn't buy an apple and run windows VM on my mac just so I could still use CS5 for windows either, that would seem like odd logic. That would be my biggest concern.
