The first thing it did was pop up with a dialogue asking for my zip code. Less than thirty seconds later I got this little window on my screen and it updates the weather every time you power up, in real time. I haven't even started on the other stuff yet. And accurate ... yeah. Wind chill, barometric pressure, dew point, visibility, the whole nine. makes Acu-Weather look like a wannabe and its unobtrusive which I like very much!
