New York Times:

Some features in Samsung devices that Apple objects to are part of Google’s Android operating system, by far the most popular mobile operating system worldwide, running on more than a billion devices made by many manufacturers. That means that if Apple wins, Google could have to make changes to critical Android features, and Samsung and other Android phone makers might have to modify the software on their phones.

Given the incredible complexity of bringing a new Android OS to market, and the glacial adoption rates, this could be crushing. But I suspect the change will either be delayed to death, or be solved in a cross-licensing or financial arrangement.
