The only reason I don't use an iPad as my music tablet is the operating system. I have been using my Surface Pro 3 for years with no problems. I am thinking about a Surface Pro 8 as it has a headphone jack that most have discontinued. I have music programs like Notation Composer that I wouldn't give up.
There are, of coarse, many options, but this is mine.
