@Sputnik. I agree that i have been trying to use the MAC with my PC mindset. Unfortunately, with 20 years of PC behind me and 2 months of Mac its a bit hard not too.
Unforunately, freehand MX has been discontinued and i believe replaced by illustrator, but hard to get my wife to learn a new product. (Adobe still sell Freehand MX which is a cheek)
@macboer, it seems your biggest problems are going to be three fold.
1. Mail conversion of exising mail boxes. (PM if you need to do this.)
2. If your IT guys are purely PC specialists, getting network and general support might be a problem .
3. Users will miss the right click on the mouse.......
