Far be it for me to recommend software piracy, but if possible I do like to try expensive software before lashing out loadsa money on it. So I borrowed an original copy of Adobe Acrobat and tried it. I found it a massive consumer of resources - it slowed down my machine considerably and caused all sorts of nuisance and interference with my MS Word programme. I uninstalled it; for all the use it was I'd never bother buying it. Open Office works fine for saving as PDF.
