I'm a piano acompanist/concert pianist and at the moment i'm using a Samsung tab FE 7 with a bluetooth pedal in all my gigs, loving it, never had any problems with it but I want to try a bigger, e-ink tablet. I found BOOX tab X and it is what im looking for but i'm concerned because there are mixed reviews and there is no musician commenting about that tablet. Has anyone tried the tab X with mobilesheets and a pedal? Is it responsive? Is it worth paying that much or I'm better of buying an ipad or better samsung tablet?
I would appreciate any input, I cannot find almost no information on the internet.
