Interesting discussion between Bradley Horowitz and Tim O’Reilly re Google+. Tim O’Reilly makes interesting point about an apparent consolidation in the industry along certain stacks e.g. Apple, Google and Microsoft. He quotes his own preference for using an Android phone because it integrates more effectively with the google calendar. This has been my own experience also – though as an external consultant do find myself needing to work across more than one stack – depending on client preferences.
