I love the easy navigation and usability of the software. I have been an apple user for over 20 years and have watched their software become more and more refined. Apple OS X Mountain Lion is everything that I expect from Apple software. It seemlessly connects to all of my other apple devices. I've also had very good experience with contacting their customer support when I had questions. Review collected by and hosted on G2.com.
