Rubin says that if other manufacturers want to be as successful as Samsung, they will have to find their own way to do it. In other words, Samsung's competitors shouldn't count on Google to close the gap between Samsung and the other Android phone producers. Rubin also made a point of noting the investment Korean based Samsung has made in making its name a world power. Currently, the Samsung Galaxy S III and the Samsung GALAXY Note II are the two models that are driving Sammy's success in the Android space.
In addition, talking about the open source Firefox OS, Rubin said that it might be able to bring the internet to regions of the world where Android can't help. Because of certain hardware requirements that are needed to run Android, emerging markets might have to rely on another mobile OS to bring less expensive phones to certain regions. He added that getting those people to the web that might otherwise never get a chance at using it, can actually help Google.
Rubin also welcomed the opportunity to compete with another open system than with a closed one. "In general, I feel friendly toward them… open is good. Competition is good. We built Android because there was no open operating system," he said.
