My Android phone's weather widget gives me the current temp, the daily high and low, and a general icon (sun, snow, freezing rain). Here in Massachusetts, it's accurate enough to be useful.
The spatial resolution on the weather data is pretty good; it distinguishes between my town and the next one over, and gives separate forecasts. The forecast is always a little different at home than at work (about 30 miles), but not too bad. Maybe it'd be a problem if I lived in the Bay Area, where the punchline of the "don't like the weather?" joke is not "wait 5 minutes" but "move 5 feet".
