 I put this very short video together that looks at the speed of apps opening on the new MacBook Air M1 silicon notebook and a 2016 MacBook Pro. So first I've got Microsoft 365 and on the M1 MacBook Air that is the universal version of Office that's in beta at the moment. And obviously Intel version on the 2016 MacBook Pro and then opening a file in Keynote on both the MacBook Air and the 2016 MacBook Pro. And as you can see it's not huge but definitely the MacBook Air is a lot snappier in terms of opening applications and files from the desktop.
