People who own Apple computers tend to be rather loyal to the product line. Some might even say they become Apple Mac Freaks. Whether you have a top of the line Mac Pro, or MacBook Pro, an entry level iMac, or even an older Power Mac or iBook, you're bound to become a rabid fan.
You'll dread the times that you have to go back to using your Windows PC, although with the new Intel Processors, now you can even run windows programs right on your Mac. So you can give that old Dell to the kids. :-)
Of course, you'll also want to get a colorful sleeve for your MacBook, sink it with your iPod, and if you're really lucky, download new hacks for your iPhone.
The possibilities are endless.
