I actually didn’t expect this to come right from Apple, but it makes a huge amount of sense for them to release it officially, and it was inevitable someone would do it: Boot Camp lets dual boot your Mac into Windows or MacOS, in beta now. The program is free, but you’ll still need a copy of Windows XP SP2. It basically solves the problem of people who are hesitant to switch to a Mac because they have one or two programs that they have to use that only run on Windows. It’s not a perfect solution, because you’ll still have to log out of your MacOS session to use Windows, but it should get people pretty close. It also opens up the option that you can have people in the house sharing the same machine, some of whom only use Windows and some who only use MacOS.
