So whether you’re browsing the web, checking your email, or video chatting with a friend on another continent,* getting things done is at once easy to learn, simple to perform, and fun to do. Of course, making amazing things simple takes seriously advanced technologies, and Mac OS X is loaded with them. Not only is it built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability, it also delivers incredible performance, stunning graphics, and industry-leading support for Internet standards.
