This doesn’t make any more sense than Windows phones made. They required way too many hardware resources and power to run a system that is designed to do a ton of things on a ton of different types of hardware. Handheld hardware needs specialized OS optimized for the platform and I doubt this will do that. It will likely have a ton of RAM and processing tied up in OS activities just like windows phones making everything slow and/or battery life really bad, but still not be able to run a lot of the stuff that would make this all worth it. Better to start with a more modular system like the base linux kernel and add only what is necessary than to start with the idea of supporting a ton of software and sacrificing the real purpose of the device (handheld gaming) to do it.
