Part 1 mentioned how you can continue using your Windows skills by installing Parallels or Bootcamp on your Mac. In Part 2, I gave you some easy tips on how to convert yourself by getting used to Mac OS hotkeys. Part 3 of switching to the Mac, is an informational guide of some of the cool applications that are available for your Mac.
I'm going to just touch up on a few of the applications, but Peter Baer wrote a blog entry of tons of applications for a Mac in: Business, Communication, Development, Editors, iTunes/iPod, Miscellaneous, Multimedia, Networking, Organizing, System, Utility, Web, Widgets.
