Concern had been raised in the industry that earlier MacBooks would be left behind in terms of interface, requiring a hardware refresh that has yet to manifest. Multitouch on these systems is currently limited to scrolling through browser windows, or performing right-click commands. The addition of Air-like controls to the Pro could prove especially useful, allowing new commands in programs like Aperture, Final Cut and Photoshop. Update: T3 has pulled the article from its website, a move that suggests it was posted in error. Previous information from a teardown by iFixit suggested that the Air's multitouch is handled by a Broadcom chip, the same one used in the iPhone and the iPod touch.
