I love my 12.9” iPad Pro. It is the 2021 version, the first one with M-chip in it. This is how I use mine.
It is always with an Apple Pencil either laying next to it or attached to the side. And I always use one of those Apple accessories with it. Either a Smart Folio or the Magic Keyboard. It is that ridiculously expensive keyboard thingy that turns it into a kind of MacBook.
My iPad is usually in the Smart Folio most of the time, and I put it the Magic Keyboard case when I’m using the keyboard or trackpad for as long as I’ll be using that. And I usually only bring it when I’m not also bringing my MacBook Pro. But I always bring it in any situation where I have my iPad and would like to type more than a sentence or two.
Part of me wish there was a way to kind of have a Smart Folio that I didn’t have to take off when I wanted to use the Smart Keyboard.
