If you own any of those devices you should be very excited. Matt knows what he is talking about when it comes to games and more importantly what makes games fun to play. Apple has always lagged behind in gaming and this is a very positive step toward them competing in the games market. Apple recently released info on it iPhone OS 4.0 and one major addition to it is the Game Center. It will be a very Xbox Live like service that will act as a social network, matchmaker for online gaming and will offer achievements. We don't know much more about it right now.
What does this mean for mobile gaming? A major company like Apple getting into a new market is always a big deal. You have always been able to play games on Apple computers and the iDevices, but this new Game Center is the first real maneuver directly into the territory of the Nintendo's and Sony's of the hand-held gaming world. Sony is already struggling with its PSP, while Nintendo is the current giant of the landscape. Nintendo has stated that they are not concerned with any competition the iPhone may present. I think Nintendo should get concerned. As a consumer looking for the most for my money, a device like the iPhone or even just the iPod Touch does so much more than just play games. Nintendo is currently working on its successor to the DS. For Nintendo's sake I hope it's more than a sleeker DS with 3D capabilities.
Too bad I don't own any of these devices; my birthday is November 28 if any of you were wondering :)
