Clearwire seems to appear out of everywhere these days in Seattle. One block away from our office is a huge sign, commercials abound online and they seem to have a store in every major mall here. They appear poised for an IPO later this year and have set the terms this week.
Although finding mixed reviews online, we are considering going with Clearwire as our ISP. Some of their customer support issues need to be resolved, for instance, today we called to inquire about service and were put on hold for 30 minutes.
If they can fix these problems, and some of the update problems I've heard of, I think they'll be able to give the telcos and cable companies a real run for their money.
