MacFixit reports that Apple plans to offer its 802.11n enabler for a $5 fee. It will enable 802.11n on Intel Core 2 Duo iMacs (except 17-inch, 1.83GHz iMac), Intel Core 2 Duo MacBooks, Intel Core 2 Duo MacBook Pros, and Mac Pros with the AirPort Extreme card option. They will also bundle the enabler with the new Airport Extreme Base stations. This is not a huge amount of money, but one wonders why the enabler wouldn't just be a free download. I'm not sure the "Sarbanes-Oxley Act" explanation offered by one of the comments holds much water. On the other hand, it's not going to be a huge profit item for Apple either.
