Actually, with a Genos, you would want a windows 10 tablet..
Not just as a musicreader.. but also for Yem...
And a whole truckload of windows compatible 3rd party free support programs for yamaha arrangers.

On top of that a windows tablet runs cubase or another daw
And you could even expand your Genos with software vst instruments and sounds
And last but not least, V-console can also run on a windows 10 tablet..

Its an expensive choice, but you get so much more in the end.
