With the introduction of AirPort Extreme 802.11n base stations, Apple announced that the majority of its current machines are compatible with the draft of that standard via a drive update. On the other hand, the MacBook and MacBook Pro Core Duo aren't likely to get compatible Airport modules. For Apple, these machines are condemned to always remain at 802.11g. This is even more annoying if you buy one of the new base stations and decide to run in a mixed g and n wireless mode, because in this instance the performance in g will be degraded.
