I use a book-edge scanner at the library. It goes MUCH faster than the HP printer-scanner-copier I have at home, and can scan to the center of the book. I have scanned hundreds of pieces, and one vocal score of 203 pages.
I scan to PDF in grayscale, high quality. The result looks great on my 13" tablet. On this scanner, black-and-white makes every noise speck be a solid black spot, which is visually distracting.
I also download PDFs from the Internet. Some of the larger ones (e.g. 116 pages) load slowly (3-5 seconds for the first page or two, after playing a page it's fine).
