According to ComputerWorld, the number of "public" Wi-Fi hotspots has surpassed 100,000. This is almost a 100% increase from the number of public hotspots at this time last year. Some interesting factoids I found are:

1. The U.S. leads the world in hot spots, with 37,073
   
2. 8,118 of the hot spots were free, and 92,237 charged fees for access
   
3. HotSpots are dominated by hotels (26,330) and restaurants (19,653)
   
4. Cafes are a separate category, with 13,815
   
5. Pubs make up 6,285, while all other locations total 20,445
   
6. 30 municipalities are up and running and hundreds are being implemented
