Desktop PC user thinking of making the jump. I've done all the consideration regarding the difference between the two platforms, and aside from the cost difference I am comfortable with a move to Mac. I'm not too keen on the iMac as a solution, so I was hoping to hear from anyone that uses a Macbook Pro + monitor as their main editing workstation. Any pro's / con's? Looking at the performance of the new ones the MBP seems to rival desktop performance.
