MarcoPolo<\/a>, “context-aware computing for OS X” appeals to all three great virtues of the programmer: Laziness, Impatience, and Hubris. It makes me want a Mac notebook. Unfortunately, Pro\/E, ANSYS, and other necessary tools for my regular work would mean I’d end up dual-booting the Mac all the time. And I’d miss my port replicator and its enabling me to have one connection to the monitor, keyboard, mouse, network, etc.<\/p>\n

So, why not build a MarcoPolo for Windows? I’ve not yet found one, but I’d be more than happy to be proven wrong there. In the meantime, I’m working on a Python\/Windows proof-of-concept that could be the groundwork for a Windows analogue to MarcoPolo.
