If you're not "bilingual" in terms of using both PCs and Macs you should be. The PC is fading while Macs continue to rise in popularity (helped by iPads, iPhones, iPods, etc.).

Get to know them both and you'll be better off. And buying into a Mac doesn't have to be expensive - you can pick up used Macs (iMac desktops and MacBooks/MacBook Pro, etc.) pretty inexpensively as the iGeeks all upgrade as soon as new gear comes out. Their loss can be your gain.
