Laptop Market share at a local coffee shop

I'm at Dunn Bros Coffee in downtown Minneapolis. This coffee shop is notable for both good coffee and free WiFi. Over the course of the afternoon, I've seen 2 dells, one thinkpad, and 4 recent-model powerbooks. I find it interesting that there are more and more aluminum powerbooks cropping up. I wonder if Chris Sells had the same experience when he came here...
