I don't think msg 6 is wrong, the "standard" will be what people use. Currently, 802.11b is the "standard". "g" will follow as people build out and improve their networks.

For many, the fact that 2.4GHz is long-range is one of the real benefits. Also, devices in the 5.8GHz are becoming more pervasive as well. The hopes of monopolizing a public frequency are short-lived.

I believe if you check on the new Mac notebooks, they've also improved the antennae issues.
