MOTO Development Group posted a very interesting story on their labs.moto.com blog today revealing the results of their touchscreen accuracy test. They took the Apple iPhone, HTC Droid Eris, Motorola Droid and Google Nexus One then performed a simple line drawing test using their finger. The results showed the Apple iPhone to have the more accurate touchscreen. We've embedded a video of theirs explaining the tests below as well as a screenshot of the results for each phone from their web site.
