Hi Guys, My mac is due to arrive on Friday! Do most people have a copy of windows setup on their Macs using bootcamp? This seems to be regularly talked about and wondering if it's essential? Just how many programs out there can't be installed on the Mac? I would have thought most programs now offer an option to be installed on both Windows and OS X. If it is recommended to have windows installed, do I have to purchase another license from Windows or can my current key from my laptop work?
