there are a couple 3rd party apps that turn your ipad or iphone into a controller for your mac but i think that the apple TV might become a game console as well kinda like what Mircrosoft did with the xbox turning if from a gaming unit into a entertainment system for media streaming ect and apple is taking the ATV and bringing gaming to it. I can see it linking to the games that are in your itunes lib or transposing the games on the ipad or iphone to the ATV via airplay and turning the iphone into a controller.
Apple did dabble into the gaming in the past but failed remember these?

oi this old unit is selling around $500 used these days
Yea I use my iPhone for steering on Real Racing for the Mac. It's awesome
But yea, there's a few key differences between that set the Apple TV way apart from the Pippin. The first is price. According to Wiki, the Pippin launched at $599. The Apple TV is an amazing steal at only 1/6th the price of that as well as a fraction of the price of competing consoles.
And second, the Apple TV has already sold units in the millions. Again, according to Wiki, the Pippin only managed to sell 42,000 units during it's run. Apple already has a massive install base, as well as the rest of the iOS users who may be affected by the halo affect. Tie in iCloud support and even "universal" app support between iOS and Apple TV apps and my, Apple could already have quite a lot of content and users on the plate.
Apple may have learned much from their mistakes so I'm very optimistic about Apple TV's potential.
