What is the difference between the older and newer models of Sony robot dog?
Some people have mentioned the ERS-110 that went out on June 1st. This is the ERS-111, which comes in two colors. It also has a shorter tail that allows it a different variety of expressions that we did not see with ERS-110, and shorter ears, allowing them to be full of expression. And of course, butt-loaded memory sticks.
