Re: Mac?
The Mac version is missing a lot of features, especially Outlook. I hate it when my boss comes up and says, "how do I get that in Outlook?"
"You can't."
"But my assistant has it."
"Yes, but she is using Windows."
It also has some problems accurately display presentations, if textboxes are filled to the limit - the OS X rendering of fonts means that boxes that look fine on Windows sometimes wrap under OS X.
