I was trying to print maps from USA Atlas. Formate was not recognises on mac so could not use shared folder. then could not reach printer since USB. Then i thought wonder how you copy screen in window. So tried the mac keys command-shift-4 and wow it made picture of it right on mac desktoo and i was able to print it using mac OS. Others may have known that worked already but i did not. Also the screen copy keys work too command-shift-3. the best part is it works in full screen mode too. Probably old news to most but was life saver for me. Think that might be the deciding factor for me about buying this. Mapping program is te reason really wanted windows , since they dont make it for the mac anymore,
