I currently have a MP and MBP. Each has Fusion 3 and each has WinXP SP3 running. Since it's such a PITA to make the jump from XP to Win 7, I'm thinking the easiest upgrade is just add a second VM but I think this requires me to buy full copies of Win 7 (I want Professional given both machines are for my business). MSRP is $299 for a full copy of Win 7 Professional. Rather than paying $598 for 2 copies, does MS offer a 2 or 3 license version of their OS (kind of like Apple's "family pack")? For example, I know they did a 2-license version for the just released copy of MS Office 2011 for Mac.... If not, what's the easiest way to upgrade 2 machines to Win7 Professional?
