Writing a mobile app using Flash? Want to win a cash prize? Then why not enter the Adobe AIR App Challenge!

Sony has partnered with Adobe to offer a grand prize of $100,000 for the best application optimized to run on their new Android-based Sony Tablet S1 and Sony Tablet S2 tablet devices. The competition has been running for a few months now but with the final app submission date set for November 11 there’s still plenty of time to get your entry ready.

There’s actually $200,000 worth of prize money up for grabs and by entering you also have a chance of being selected to receive early access to the Sony S1 and S2 prototypes! I’ve actually been meaning to blog about both tablets for a while now as they certainly stick out from the crowd. The S1 in particular looks like a particularly attractive device and its 9.4-inch screen might just make it a little more comfortable to hold than the iPad.

The competition is open to residents of the USA, UK, Spain, Germany, Italy and Japan. Oh and your submission can be created using either Adobe Flash Professional, Flash Builder, or the Flex SDK. So what are you waiting for? There’s fame and fortune to be had.
