Apple's new Shuffles may have taken the limelight this morning, but in addition to the bite-sized players Apple officially released its 802.11n Enabler. The $1.99 software download unleashes your Mac's hidden talents, letting your Core 2 Duo-based machine access 802.11n networks. You can also get the update by purchasing the new AirPort Extreme. Whatever route you take, just make sure you obviously have an 802.11n network to take advantage of the speeds and range.
