iPad as piano sheet

Ok, how many of you have experienced finding sheet music online, wanting to play it on the piano but never got the chance because of 
1) not owning a printer, 
2) the ink in the printer is empty
3) don't want to waste ink because it's expensive! 

So I thought for myself, why not use the iPad since it's like a mini pc which have almost all the same functions as a real pc!? And it works! It allows you to view pdf-files directly on the iPad screen! It's convenient because of the screen size and you don't have to keep a whole stacks of paper on your piano! And no, it won't fall down...well, it doesn't happen on my piano..so you may take a look at the stand for sheet music on your piano, before placing the iPad there!
