　　An unresponsive trackpad can ruin a laptop.But how do you test for that without having access to ready-made equipment? Ifyou're Google, you build your own machine. The company's Chrome OS team hascreated the Quickstep, a USB add-on that uses a laser to gauge trackpad latencyon Chromebooks. Whenever you break the laser's beam with your finger, Quickstepmeasures the delay between that and the registered touch input. The device onlylooks for drag activity, but it's simple -- you can even build it yourself, ifyou're handy with electronics. Whether or not you're that interested, Google'sproject should take some of the frustration out of future Chrome hardware.
