I was a very early adopter of the MAcBook Pro retina 15". I got in in the summer of 2012. Love it. There are times when I would like to run windows, to do SharePoint tasks and other rare Windows only things. I tried about a year ago to put Windows 8 on, but I always had some issues. Couldnt get brightness to work, no sound, networking worked 20% of the time, etc. Eventually I gave up and did nothing. Here I am, a year later. Does a fresh Windows 8 install work better now? Should I just put Windows 7 on? How much space do you all allocated for the partition?
