We have been running winXP Pro in parallels 5 & 6, and now it's really past time to upgrade. Parallels to 7 or 8, and then windows. We are first researching whether to get windows 7 or 8 -- we have to find out if any of our "must run" pieces of windows software won't run on 7 or 8. Once we figure that out, the next question is how much money to spend on windows? Will Home work? Home Premium? Pro? What does the extra money get you in each case? Is there anything simply broken in the cheaper versions (printing? networking?) that works fine in the more expensive flavors? I'm willing to pay for what we need, but see no reason to overpay for what we don't need.
