Santa just brought me one. Naturally, I've loaded some really geeky stuff, such as Py4A and Addi. For fun, I'm slowly porting my speaker design app to the Android platform. For music, I've already found a free tuner app, and iRealBook is pretty slick. But I wonder what else I should be looking at. The Adobe reader will display PDF'ed sheet music, but is there a better PDF reader for this purpose?
