If this was the typical use case of a private person unsure whether they should use Linux for their personal computer, I’d whole-heartedly agree.
However, since OP is making the decision whether to use Linux for their business, I think they should definitely try it out first and especially try to simulate their workflow in order to ensure Linux will suit their needs. It’s one thing if your operating system is wonky while you’re trying to watch Netflix, it’s a whole different thing if you can’t watch evidence videos which will prevent you from doing your lawyer work but woopsie, you fully committed to Linux.
Definitely just try everything out before making the business decision to switch over to Linux.
