Remember how the first gen iPhone (and similar non-GPS devices) use Wi-Fi nodes to guesstimate the user's position? Snow Leopard will do that, too.
According to developers working with pre-release builds of Snow Leopard, the OS contains the same CoreLocation (Wi-Fi triangulation) framework found in the iPhone SDK, which should allow third party programmers to easily take advantage of the locational tools. And, given that CoreLocation requires no special, costly hardware, I say why not? It's sad that, even from my couch, I close my notebook to use my iPhone whenever I want to look up directions.
