I know I am going to get flamed for this question, but I am trying to understand how some people are using Parallels and why. I see so many posts about people having issues with Windows versions of programs for which there are Mac versions. Some I understand, you've paid good money for a Windows program, why pay again for the Mac version. But I see people asking about Safari for Windows, iTunes for Windows, VLC for Windows, WoW's window version, Google Earth, the list goes on. Why aren't people using these programs native within OS X itself?
