I noticed something odd the other day. The coffee shop I hang out in has wireless networking. Half of the laptop community there use some flavor of Mac (an even split between iBooks and TiBooks, with some older Macs thrown in). I also hang out in the local public library, which is wired for 10BaseT. The odd thing is that I don't see Macs in the library, either in the morning, when the adults hang out, or in the afternoon when the high school kids come in to do homework. I've made the rounds a couple of times to check. Dells, Sonys, Toshibas, HPs, Compaqs, Thinkpads, but no Macs.
The signifance of this eludes me.
