WiFi, 3G, WiMAX and Fixed Wireless...
In the (uninformed?) press there is endless debate about what wireless technology will 'win' at the end of the day. Somehow it all seems obvious to me...but then again, it IS my brain...so it would seem obvious to me.
WiFi aka "Poor Man's Wireless"
Great for coffee shops and stealing it from (mostly) unsuspecting non-tech types who leave their home router unsecured. Also good for those cities that somehow believe blanketing their downtown or the entire city with WiFi will make their city more attractive and a better place to live (which in my opinion will result in class action lawsuits by taxpayers in jurisdictions where they may have footed a portion of the bill). Dailywireless reports that there are over 300 municipal wireless WiFi systems in the USA!
