Anyone with a yen for disassembling computers discovered last year that Apple had jumped the gun on wireless standards by including Atheros and Broadcom 802.11n, or “N,” chips into some Intel Core 2 Duo models. This stole some of Apple’s thunder last week at Macworld Expo when it formally announced its adoption of 802.11n and the wireless networking standard’s 100 Mbps-throughput. But what was more surprising was the company’s willingness to commit to a standard that’s a year from completion.
