I hope I don't offend the forum gods with these questions, since I know some of this is answered by using the search button, but here goes: I'm a 13 month Macbook user and I've had an iPhone since they dropped the price in September of their introduction year. I love my Mac stuff. My situation is this: My work-supplied Dell too its last crap and lost my data again. (really wish Gates would figure Time Machine out). I'm sick of it. I use the Mac for everything but my most important role which is demonstrating automotive diagnostic equipment. 95% of Auto diagnostic software works through XP and the other 5% is Windows 7. Mac is out in the cold. I need to know how well other USB based interface modules designed for XP will work with the MBP running XP. Would it work to run a parallel desktop type program, or set up a second operating system in Boot Camp? Most tools are a small pass through box that connects to the car and to the laptop by USB. Second question is which would be better for what I want to do: Boot Camp or a parallel desktop?
