I do not do Office 365. MS still sells the non-sub mode but doesn't like to announce it. They want us to pay monthly. You can still buy it, and even sometimes find licensed deals on places like Groupon (yes, legit, but do your due diligence. I did it a year or so ago and MS recognized the Office for Mac license and I had zero issues, but I did fully vet it before hand). I also just got a new MB Air and will be buying another copy. I detest online subscription models of anything, so I suppose I am a dinosaur too!
