Just a few months ago, some companies developing applications for App Store they promised users that they will be able to continue on an iPad tablet a game started on an iPhone and vice versa. Basically, you buy a game on the iPhone, it is automatically installed on the iPad, you start playing a few levels of that game on the iPhone, you make some progress, but then you want to switch to the iPad. If you don't play a title like CSR Racing, then you will find with disappointment that your profile has not been transferred from the iPhone to the iPad when you open the game, but if you play that title or another similar one, then you notice that the moment you open the tablet you have all your profile available along with all the progress from game.
Many developers have promised to implement such systems in games, very few have kept their word and I am disappointed by those who haven't done it yet. I believe that such a system is not only useful, but mandatory for any self-respecting manufacturer because it gives the user the opportunity to experience the game on several mobile terminals, but without losing functionality. I hope that by next year most important games will have such systems included, but they are difficult to develop and not everyone can afford to run them.
