Recently Apple upgraded the Airport Extreme to 802.11n Draft 2. Does this mean that it is possible for Aple to upgrade the router to 802.11n whatever when it gets ratified? When 802.11g was not ratified, was there an Airport Extreme? And if there was then did Apple upgrade the draft 802.11g to the ratified one via a firmware upgrade? Will it be safe to buy an Airport Extreme and not worry about 802.11n getting ratified because Apple would upgrade the firmware?
