MOTO has done another benchmarking test comparing mobile touchscreens: Robot Touchscreen Analysis. (I wrote about the previous one here.) This time they've used a robot-controlled (simulated) finger instead of a human finger. The test involves drawing diagonal lines and looking at how linear the response is on the screen.
I think it's great to get data, but these results are being overhyped in my opinion. (And — disclosure! — I work at Synaptics, though I don't speak for Synaptics here.) This test measures one performance characteristic but misses others.
