I have a 2005 Powerbook G4 with a scrolling trackpad. A couple of days ago I got to use my brother's MB. I found that it has this really cool two-finger right click feature. That is, when you tap with two fingers, it acts as a right click, really nice. What I don't understand though is why apple didn't release any kind of driver update for powerbook/ibook owners to enable such a feature. There is a software called iscroll2 that enables such a feature but only for older Macs with a non-scrolling trackpad. And as far as I understand, it is a software issue not a Hardware one. So why can't Apple just role out some update to enable such a feature on scrolling-trackpads?. Is there a technical reason why this is not possible?. Any input is highly appreciated, Thanks .
