The PS Vita is an awesome console for homebrew and game development. I've been working on a small cross-platform game, and used my Vita to both implement cross-compiling in my build system (to port to other systems later), and develop the game for both a touch screen and physical controller. Why bother carrying around a controller, android/ios device, and cables to develop a game when a single Vita will do!

If Sony and Nintendo would release their official SDKs for these dead consoles, maybe people would have less reasons throw them away. I don't understand why they're so defensive about it anyways.
