Is this a practical example of how Google's strategy with Android is just a bit anti-competitive? Neither Palm or HP could have seriously considered licensing WebOS to compete against Android because neither has a gigantic advertising business to subsidize the cost of development. On the flip side of that how is Palm or HP going to compete with companies like Samsung, HTC, Motorola, etc who are getting their OS for free? If they skip the costs to develop their own OS and go with Android what differentiates an HP tablet from a Samsung tablet if they're running the same OS? All roads lead back to Android. You either use it or you can't compete against it.
