A multitouch trackpad, well appointed and with battery, the idea sounds good ... Having the habit of using the trackpad MacBook Air and Pro (and the trackpad an average range of PC there a few years), the precision of it is absolutely not up to standard: it is often necessary to try several times to certain multi-touch movement (at 2 and 3 fingers on trackpad often confusing), the edges are less sensitive than the center. Very uncomfortable every day. Since the transition to OS X Mavericks (on a Mac Book Air mid-2012), the driver of the trackpad seems buggy: half the time, the movements are jerky, and the trackpad has the unpleasant habit of ... click to less movement! We must then stop using it a few minutes, so that it works again less correctly for a few minutes before rebugger. And no updated driver available ...
I highly recommend, especially at a higher price than the Apple trackpad, expected quality at least comparable ....
