I was given Parallels for Christmas (I asked for it...) to install on my new Macbook. I have a windows based cell phone that I wanted to be able to load music, calendar, etc and be able to work it with my Macbook. Curious to know what Windows OS I should get to load in Parallels? I won't be needing anything exotic for my job or anything, just basic Windows functionality. Been so long since I worked with Windows, don't know which would be ideal for me. I have seen 32-bit-/64, Basic, Premium, Windows XP or Vista, etc. Can anybody give me their best recommendation??? Thanks...
