This strikes me as incredibly naive. Since when is "reaching for your mouse" a bad thing when using a laptop? If adding touch screens to laptops was all anybody needed to do to improve our computing experience Microsoft would have run away with the tablet market years ago.
Pinching to zoom is a pattern that makes sense on tiny mobile devices, not large laptop screens. If I have to zoom in on a webpage to make it usable on my laptop, it's time to increase my font sizes. Zooming into a photo perhaps makes more sense but why not simply support the pinch gesture on the trackpad like Apple does on it's Macbooks? Instead I need to gorilla-arm it every time I want to zoom into a photo?
Tacking multitouch screens onto traditional laptops does not a better computer make.
