There is an interesting article on iLounge
. Interesting in the "WTF?"-sense. If you have a Core 2 Duo Macintosh, the built in wlan-card is capable of 802.11n. This capability can be unlocked via a software update Apple distributes with the new AirPort Extreme Base Station. Or they will sell it to you for $ 4.99. Why they don't give it away for free? Because of the Sarbanes-Oxley Act. iLounge cites an Apple representative: "it's about accounting. Because of the Act, the company believes that if it sells a product, then later adds a feature to that product, it can be held liable for improper accounting if it recognizes revenue from the product at the time of sale, given that it hasn't finished delivering the product at that point." Or, to sum it up: Look at the crazy monkey!
