Well, Christian, unfortunately one difficulty with that is that this is all changing so much so fast it’s hard to keep up, even online. 🙂
Georgina, one thing I should have mentioned is that scanning in printed bought music probably has all sorts of copyright ramifications. It’s not a problem for me since I mostly play my own arrangements, and they exist in Finale, which makes very nice pdfs very easily. But I have a few important things I did in MusicTime Deluxe before I got finale, and getting those pieces into PDF (since I can no longer open the original files on the computer) is time-consuming and labor intensive, even on a mac, where you can easily make a pdf from any file in any program.
