As a developer, I wish that were true. I bought a Raspberry Pi, and just opening a window with OpenGL in it was frustrating beyond belief. You can apt-get install SDL2, but like most packages it hasn't been adapted to the Pi and won't work with GLES. So you have to build it from source. And even then I couldn't figure out how to stop keyboard input from my SDL window from leaking into the terminal that started the game. And so on... I ended up giving the Pi away.
And that was ~a full year after it came out, I never buy things on launch day.
In Xcode, it takes something between 5 and 10 clicks to create a working project for OS X or iOS (with OpenGL or whatever framework you want to use).
The developer experience is a big part of what makes the Apple TV what it is. I'm not saying it's perfect - I can't believe the App Store doesn't allow for time trials yet - but it's really, really easy to beat the developer experience for any other living room device.
