I don’t classify myself as an early adopter, I usually wait until a new technology has been out a while and the price has come down a bit before I jump in. Consequently I rarely find myself ahead of the certification curve. It is more a measure of the length of time that the IEEE certification has taken that I am already on my second generation of 802.11n router when the standard has only just been approved.
Considering that Draft-n wifi gear has become almost the defacto standard for most new networking gear it was only a matter of time. Some time was lost deciding between one of three proposals until the groups behing them decided to merge into one. A patent case from CSIRO on technology used in the draft standard also delayed things to some extent. Regardless of the delays n is now a standard. All we need now is something faster.
