My main computer was a PC but a few years ago, I purchase a MacBook Pro because of it's size and many of it's features but being a senior citizen, my learning curve was not what I thought so I decided to see if I could install some Microsoft programs but realized I needed some software to help me accomplish that. I tried a few options and when I read about Parallels I decided to buy the program and it did exactly what I wanted. I now have all the Microsoft compatible programs on my Mac and with Parallels they work perfect. My PC is a bit of a powerhouse machine but with the latest version of Parallels I think my little Mac works as good as the PC.I would recommend Parallels to anyone in the same boat and my only peeve is that unlike Apple, Parallels charges a hefty fee for upgrades but I have been upgrading anyway because each upgrade is definitely better than the last.
