I am an apple fanboy, have been since I got my first iPod (mini) years ago. This has expanded to the fact that I now have at least 5 apple manufactured gadgets within my sight right now, the computer I am typing this on included. I also fancy the couple of classy (yet extremely nerdy) Mac shirts that I do own, and I wear them frequently. Having said that, Coty Gonzales has gone and brought a ton of Mac centric shirts on his T-Shirt blog. Some are well-designed, obnoxious, funny, and others are just plain awful.
The dude posts some pretty slick stuff too, I would suggest checking his other posts out.
