Also, you may be sharing your device with someone else - maybe two horn players reading off the same screen or, as often in my case, the bass player might be looking over the pianist's shoulder. My first Android tablet had a 10.1-inch display, which was plenty big enough to see. But move a little to the left or right and it was unreadable. For high-quality viewing angles comparable to an iPad, be sure to get an IPS (In-Plane Switching) display.
