Sony isn't like other hardware-focused manufacturers. Sony is more like Amazon; Sony can provide content to go along with their tablets. The Playbook bombed (similar hardware to the Kindle Fire), practically all Android tablets bombed (similar software to the Kindle Fire) and yet when Amazon stuck their name behind one it's now selling millions. If Sony bought webOS and put up a proper content store on it, from their movies to playstation games, they might be able to get the ball rolling. Of course Sony hasn't actually been able to do that on Android either, and I have little faith that they'd be able to execute on webOS, but the potential is there. They are certainly a better fit than HP ever were.
