I play a trick the neighbor who likes to filch my wifi connection. I leave my connection open for five minutes Monday mornings. This neighbor’s computer got registered on my network the last time s/he logged on to my wifi network, and naturally it showed up on my Mac as a computer on the network. That’s when I noticed the icon that Apple uses to distinguish Windows computers on the network. It’s the blue screen of death!
Of course, Macs are often susceptible to the spinning beach ball of death, and Windows 7 may arguably be more stable than Apple’s OS 10.6, Snow Leopard. Nevertheless, it’s funny to see these little jabs in OS X.
