I wouldn't have a problem developing games for the WikiPad. It's all my dreams come true. Though I've heard (on this board at least) terrible things about the Google Go (assuming that what's needed to develop games on the Android).

Well, here is my list of pros for developing for the Ouya:

1. It is a new market (alternative home consoles), and to create a good IP in a new game market (similar to the early days of smartphones with iOS leading the pack) is a very good way to get your foot in the proverbial door and gain a new and loyal audience. It is also great for game visibility for this same reason.

2. It is a home console. For the first time, you can (without extensive registration) develop for a console with locked in hardware and a unique controller, so there is no platform fragmentation, no driver issues, no porting issues, and there is really no need for extensive hardware support.

3. It is cheap. This is one of the biggest boons to the Ouya's existence. The low price tag and functionality of a console for the TV with a controller will attract a new, colorful, and potentially fruitful market, not just "the core" who buys the same games every year. The industry is being killed by "the core" and its expectations and purchases. New markets that aren't very much into games (including but not limited to casual players) would probably find a 2D indie sidescrolling airplane game funner than someone who expects to go out and buy a 3D AAA boob-frag-kill festival each year, because they have different interests and come from different tastes in being entertained.

4. It could go to retail sales. This would be maybe the only way to attract said new markets. This may in fact make it successful. By retail, I mean shelf space, not just online stores from Target, Best Buy, etc. Ouya already has that.

... and the cons:

1. It is vanilla Android powered. Android is messy. It is not only messy, but it is a smartphone operating system that is made to work on thousands of different devices. It is not by any means optimized for games. Battery monitoring, 3G network connection status, text message buffers, etc. take up more memory and processing than I would care to waste. The NDK isn't something to brag about, either. Many games that are made for PC are not made in Java. Yes, there are a few (notably Minecraft), but Ouya should have tried a different approach on modifying it to cater more to native development, perhaps not requiring Java/JNI usage at all. I might be biased, but I hate Java programming, messy API's, and driver issues.

2. They follow a mobile iteration strategy. The developers of Ouya recently stated that a new version of the console will come out every year, akin to mobile phones and tablets. They are making a game console not a tablet/phone. Most consumers are looking for a console like the Xbox or PlayStation that only cycles once every 5-6 years. This will be a major obstacle in attracting said new markets, and may be the one thing that could make Ouya fail.

3. The specs. I am by no means a "graphics whore", nor are the owners of the Ouya going to probably be. But, only 8 gigabytes of hard drive space for a console that runs on digital distribution and has a free trial of every game is completely insane. Not only would this generate intense competition for hard drive space (as if purchases weren't enough), but this would also be yet another reason to NOT buy it. Also, the system's main processor is a Tegra 3. Nvidia's Shield, which is basically the same thing but handheld and a bit pricier, has a Tegra 4. That isn't going to end well for the Ouya.

4. It might NOT go on retail sales. If it doesn't go on retail sales, I can see it being one of those niche gaming machines that no one cares about that you see maybe a few nostalgic posts on /r/gaming (Reddit), not dissimilar to that old vector graphics game console from the '80's.
