Correction: Apple’s MacBook Air multi-touch is not all software-based
Wednesday, February 13, 2008 - 04:26 PM EDT Chris Foresman has updated Ars Technica's article regarding their coverage of T3's claim that MacBook Air's multi-touch was 100% software based which would have meant that MacBook and MacBook Pro units could have be given extended multi-touch capabilities via a simple software update:It appears as if the original article at T3 was likely taken down because it was incorrect. As we learned from the iFixit teardown of the MacBook Air, it makes use of the same dedicated multi-touch chip as the one found in the iPhone. We are unsure as to whether T3 misquoted an Apple spokesperson on this issue or whether PR was merely confused. Either way, we still believe that Apple plans to put larger multi-touch trackpads in its other Macs!

That's ok. Wasn't fussed about having it in my Macbook anyway. I wouldn't have paid the fee (if there was one), so I doubt I would have got it anyway.
