My tip is don’t obsess too much about if you’ll find replacement for this software or that software, the moment you’ll need it you’ll try and you will definitively find alternatives BUT it will take time to get used to it and it’s the way it is.

The more you stay on the new system the easier it will be. I switched my desktop recently and I had the temptation of going back but I stuck to it and now I don’t have the temptation, but I need windows for stupid whatsapp videocalls though.
