GPS has made life dramatically different (and, yes, better) for many of us, but it's not the only way to get location info. Windows 7 has a built-in framework for sensors that is only just now getting some developer love. Take a look at GeoSense, a nifty, free tool that pings local Wi-Fi networks, cell signals and other stationary devices to get a lock on your computer's current location. It's slick and seamless, and there are likely to be quite a few apps making use of it soon. Here's how to get it:

Enable GeoSense by opening the Control Panel, selecting "Hardware and Sound," then "Enable location and Other Sensors." Step 2: Enable GeoSense.

Tick the box next to GeoSense, then click "Apply."

Check it out by downloading this cool Google Maps client that should very quickly bring up your current location and let you search for nearby amenities and services--great for lost travelers! Step 4: Check GeoSense.

I hope to see more developers integrate GeoSense into their apps. Time will tell!
