I have parallels because Quickbooks is not multi user on OS X yet. It will be soon, then I am done. Office on OS X blows away the windows version. I have a multi user environment and all my windows bigots have since become OS X advocates. Windows is garbage and you know it. Want me to give you an Apple so you can see for yourself?
So, you have to spend extra $ for the Apple hardware, $80 for parallels.. then you have to buy Vista... Then You have to buy , Office.. Why not just get a PC and be done with it?
1. Same hardware at a cheaper price
2. no need for parallels
3. Vista is included in you're hardware when you buy then system...
4. Office is the only thing you would need to "buy" get the "home basic"/"student" version and you're set...
