I don't know if I'm the only one, but the biggest problem of google (which is the same as microsoft), is the unified account system. It's very complicated to switch from business to personal accounts. And that creates a lot of friction for me.

Can you use two browser profiles, one for personal and one for business? Or, if it goes beyond the browser, perhaps two OS users?

Container tabs on Firefox are great for this situation. Unfortunately however if you choose to go this route performance on Google's webapps is not as good as chromium-based browsers.
