You know good and well you were instantly jealous of the multi-finger gesture support
announced for those minty fresh new Mac laptops
, and if you're finally ready to ditch that envy you've been harboring and just get even, have a look. Without even resorting to gangsterism, users of pre-October 2008 Apple laptops can get the four-finger Exposé and Application Switching working -- all's that required is the install disc from a unibody MacBook, a little tweak of the registry and a pinch of patience. We can't say for sure how far back this hack will go (we're guessing your PowerBook G3 is out of luck), but we do know that it works just fine with a January '08 MacBook Air. Give it a go if you're a risk taker, but don't blame us if your atoms start to melt.
