I noticed the older Sony a81x series is using a linux based firmware, and since model is similar, but with just a larger screen it should be the same. I know they wanted to rockbox port to the a810x series, maybe we can try to also get it on the newer a72x/a82x? I think this would be a perfect candidate for rockbox as the battery life is like 36h for audio, and 5 for video. good SQ, and easy to use controls. Thank you...
