I’m using a Galaxy Note Pro (12,2 inch) and am very happy with it. I also use it for reading scores during gigs, and love the S-Pen feature as it gives more precise control when writing, drawing or using a complex UI such as the Mixing Station.
Mixing station Qu works extremely well with my Galaxy Note, even though I have a customized CyanogenMod ROM installed on the tablet. If 12,2 inches is enough for you, I can recommend that.
