Argh, I hear you. The umpteen zillion updates (always at the worst time possible) AND I was pissed that Microsoft word, excel, etc now come with a 1yr price tag. One day, when I no longer have my franchise and no longer need Microsoft products I too will be switching.
It's so terrible. Yea I had to switch to libre office a few months ago. Some formatting issues which are a drag, but otherwise free, with some syntax difference for spreadsheets and stuff. And the processor not as user friendly but if you want to make PDF's so you know it retains format probably good for that purpose. What a croc having to pay yearly fees now for programs largely written 20+ years ago.
