How I wish I had this tool last month as I was without power and telephone/DSL service at home and looking for a Internet hookup.
Sure, Starbucks and McDonalds have WiFi, but Starbucks wants $9.95 for 24 hours. McDonalds will give you 2 hours for $2.95, which is not bad.
The Windows Live WiFi Hotspot Locator will accept location information and show you the hotspots within a selected radius. You can easily print the list or map each location. Very handy.
