I use my M1 Macbook Air and my Intel Macbook Pro for work all the time. We use Office 365, Slack, Salesforce, and lots of other pretty niche software in our day to day, and it all works fine on my M1. RAM, performance, battery, etc. are never an issue at all on my base model MBA, PLUS it has a good keyboard on it. I have really grown to hate the feel of the keys on my 2019 Macbook.
