RickRussellTX writes "Comcast plans to offer 4 megabits/sec WiMAX services to customers in Portland, Oregon starting tomorrow. Branded as 'Comcast High-Speed 2go' and '4G,' the service will require a $44.99 per month subscription in addition to existing Comcast home service. For $69.99 they will offer a dual-mode card with access to both Comcast WiMAX and Sprint's national 3G wireless network. Future rollouts are planned for Chicago, Philadelphia, and Atlanta. Say what you will about Comcast (and I know many Slashdot readers have plenty to say about Comcast), this is a daring attempt to bypass entrenched cell phone companies with a direct-to-consumer wireless service."
