Steam is almost a necessity due to it being hard to get physical copies of games these days. The others I have totally avoided, though. The one I’m having trouble getting away from is Portainer for maintaining Docker Swarms. And I really wish Acrobat was less needed. One of the few things I have to have Windows for is Acrobat Reader so I can fill out documents. Even their website chokes on a lot of forms I’ve needed to fill out lately.
