I’ve found I can do 95% of what I need on a daily basis on my iPhone 8 Plus or my iPad Pro. I have moved just about everything off my Windows Surface, and if I can do my taxes online instead of Windows based software I’ll be off it totally. The main item holding me back was I used a good bit of Excel files but I have migrated them to IOS Numbers or quit using the ones that wouldn’t convert. After some 30+ years of Windows it takes some rethinking of not only how to do something or do I really need to do the way I was. But an old dog can learn new things.
