Google will clone the user interface & fandroids will talk about how Apple sucks when they are, in fact, sorta using Apple devices. In case anyone forgot, Google was ripping off Crackberry phones before 2007.
Actually, it would appear that Google has a slight lead at the moment, as their "Project Glass" is set to become a reality by next year. And I don't think anyone will be ripping off anyone else's interface- all of these devices will run on existing platforms: Android, Windows, and iOS.
