Update your wireless to 802.11n

Also hidden away in the Airport Extreme revision are software enablers, included with the base station, to field-upgrade the wireless cards in some currently-shipping Macs to support 802.11n, no hardware changes necessary -- we suspected that something like this was in the works. Per Apple's 802.11 page:

These Mac computers support 802.11n in the new AirPort Extreme Base Station using the included enabler software:

• iMac with Intel Core 2 Duo (except 17-inch, 1.83GHz iMac)

• MacBook with Intel Core 2 Duo

• MacBook Pro with Intel Core 2 Duo

• Mac Pro with AirPort Extreme card option

Mini users, Core Duo laptops and iMacs continue to chug along with 802.11g. No word yet on whether/if those enablers will be downloadable.

Thanks Jeff L. and everyone who sent this in.
