RockBox for Android works perfectly on the IBM/Lenovo Yoga 10, Yoga 8 tablets.
For reference, this is running Android 4.2 + the MusicFX android music extensions app.
I used Rasher's 800x480 which is the biggest one that also has a theme so it is ready to use.http://rasher.dk/rockbox/android/rockbox-800x480.apk
There was a slight learning curve, but my iRiver H10-8gb (previously 5, but I changed it), also has RockBox, so the only problem I had was setting the Equalizer with a touch screen is a lot like a video game, which I lost a few times.
But, everything else works just fine. And it sure does play well!
