Nexus One's multitouch confused more easily than Droid's?

Thought all multitouch-capable displays were created equal? Think again -- Android and Me has posted a rather fascinating (if not somewhat depressing) video showing a demo multitouch app created by a game developer who'd grown suspicious after running into all sorts of trouble getting the feature to work the way he wanted on the Nexus One. First up, the Droid handles the demo with aplomb -- two thumbs are recognized smoothly and consistently. Next, though, the Nexus One gets confused after a while and starts registering presses at the wrong corners of the on-screen box formed by the placement of the thumbs. There's always hope that this could be fixed with a firmware bump, but that hope looks to be in jeopardy from language posted by a Google engineer in the official Android dev forums: "...this is how the touch screen hardware on the Nexus One works (which is essentially the same screen as on the G1 and myTouch). The Droid has a sensor from a different manufacturer, with different behavior. Other phones will likewise have different sensors." In other words, Google seems to think that HTC's just using a lower-quality sensor than Motorola is. That's good news for Droid owners, we suppose -- but with game development on Android still something of a non-starter, hardware issues like this keep fragmenting the user base and preventing big-name developers from jumping in and betting on the platform. Follow the break for video proof of the wackiness.
