Where's the Mac?
Well, Don MacAskill, the reason you need that MacPro overkill is so you can run Parallels for the PC applications to which the world is still addicted. For me it's Outlook (I have to run it to schedule conference rooms and to turn my out-of-office reply on/off (or is that available in Entourage? I'll have to check)) and some of our company's own Windows Only(tm) applications. Oh, and Microsoft Project. And sometimes excel stuff that I can't do on Excel on the Mac. And some other business thingies..
