I actually have 2 tablets - one is Android and the other is Windows 10. The excuse that it's Googles fault is not good enough when the windows platform is there.
I can do anything which can be done on Ipad plus much more.
If Yamaha or any other companies refuse to use any system other than Apple then they are short sighted and foolish.
As Shuey said "All functions should be available without the aid of a tablet".
I will not be railroaded into buying something I don't want and I won't be left with an instrument that's useless if my tablet goes down - that's not progress, it's a step back.
