Those of us who use Macs know that it takes a certain level of knowledge to choose a Mac over a PC. When you go into the Mac Store you're surrounded by like-minded people who truly know what they're talking about.
I totally disagree with Jessica B, who says that the Mac Store is geared at making money off college students. College students at UW get a student discount at the University Book Store computer store... so she's way off base there.
Trust me. If you want good, solid advice regarding Mac producst, this is where you want to go.
