MOTO Development Group unveils a video and photographs of a smartphone touchscreen performance test between the Google Nexus One, the Apple iPhone, the Motorola Droid, and the HTC Verizon Droid Eris. MOTO Development Group created the simple technique so that anyone can evaluate the resolution and accuracy of touchscreen devices before they buy.
