McDonald's promised that it would be make its in-restaurant WiFi service available for free in "mid-January" and, right on cue, it's now kicked things open to everyone with a laptop and a fast food craving starting today, January 15th. That service previously cost customers $2.95 for two hours of use, and it's already available at 11,500 of the company's 14,000 locations. Incidentally, that also makes McDonald's one of the largest providers of WiFi hotspots (free or otherwise) in the United States, with the company itself claiming that no less than 16% of reported WiFi hotspots in the U.S. are located at McDonald's.
