Having made the conversion in my laptop choice around Thanksgiving of 2006, I have found the "I'm a Mac" commercials quite humorous.  It seems that Microsoft is ready to fight back.  Check out this article about how the software giant is employing Jerry Seinfield and Bill Gates in a counter-commercial advertising campaign.

What about you?  Will you remain loyal to PC or have you made the transition?  Have I mentioned that macs are immune to viruses?  Which platform do you prefer?
