I only found out about the Wikipad recently, but when I did my first thought was “Wow it would be great if this were also available for iOS devices.” And it is! Well, sort of.
Gamevice is a specially-designed control pad that attaches to the iPad Mini, effectively turning it into something like a handheld gaming device. I had the opportunity to play around with it at E3 last week (I’d have said something sooner but I was sworn to secrecy) and I was genuinely impressed. Even though the model I was using wasn’t the finalized product it still worked quite well, and tearing across the highway in San Andreas was as responsive as it could be – seeing as I was using a truck at the time, anyway.
Wikipad is planning to release two versions of the Gamevice around during the holiday season later this year: one that can act as a battery back-up for the Mini, and one that uses its own power source. Both will be available in white.
