Comcast, which announced this week it now has more Internet customers than cable subscribers, is moving on, with the new store a clear initiative to improve its customer service reputation and experience. It also is putting more resources behind its Internet service. The company said Tuesday it will launch Gigabit Pro, a super-fast 2 gigabit-per-second Internet service, in Chicago later this month. The service will be available to anyone within close proximity of Comcast's fiber network – which covers a large portion of the Chicago area — and will require an installation of professional-grade equipment. The cost of the new service has not been disclosed.
