"Customers can use the Mini DisplayPort to Dual Link DVI Adapter to connect their MacBook, MacBook Pro, or MacBook Air to a 30-inch display that includes a DVI connector," the Apple spokesperson told Macworld via an e-mail. "This includes third-party 30-inch displays, and of course, Apple's 30-inch Cinema Display HD."

Part of the confusion may stem from Apple's own product page for the adapter. The description at the top reads "“The Mini DisplayPort to Dual-Link DVI Adapter lets you connect the 30-inch Apple Cinema Display HD to a MacBook, MacBook Pro, or MacBook Air with a Mini DisplayPort,” while the overview further down says that you can connect the adapter "to a 30-inch display that includes a DVI connector, such as the 30-inch Apple Cinema Display HD."
