When I consider the cost our IT department is looking at for updating all our G-standard to Pre-N standard I don't really see how the majority of companies in the current economic status could justify the upgrade, let along implementing the system from scratch. The only reason we're even considering the upgrade is due to massive increase in laptop usage by students in the building. The man hours that go into wiring the wireless system is quite large and, while preferable for new installations when choosing one option, isn't really a viable option to the perfectly good solution of existing wired networks. Now as the economy slowly crawls back and the introduction of N-standard I definitely see where this article is headed, but my personal belief from an internal aspect facing this exact issue would be "Give it a few years, maybe 2015, and I believe wifi will be almost ubiquitous"
Also, FTA: "Many students are clueless about what to do with a patch cord to begin with. They grew up with wireless" How old are these kids? Eight?
