I know this is below the line, but how many people still use manuscript paper? I still have a big block of it, which has hardly been touched for years, as well as a couple of beautiful bound books with Florentine covers and manuscript paper, just made for you to write your songs and tunes into.
These days, if I hear a tune I like, I'll either record it and then transcribe it direct to music editing software on computer, or jot it down in my own variant of ABC until I've got time to put it on computer. And of course, now you can just convert ABC direct to notation.
