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.
