I’m a consultant. These days most things are webbased and/or MS office and very well doable with an iPad.
there are a few legacy systems that are still operated via citrix and that doesn’t play nice with an iPad. So once every week or two weeks I need to fire up the old Dell laptop and login to that.
I’ve heard the rumor that they will move everything to Azure and it will be accessible via a web/app-based thingy so then I can do everything on my iPad.
Biggest advantage is that when interviewing, the iPad is flat on the table and I’m writing with the pencil. But if I need to, I can use the Magic Keyboard and it’s almost a laptop. Oh and it has the cellulair option, no need to use all kinds of shady wifi

Oh and OLED is so nice when writing in near dark, no blooming. One more thing? When reading 350 pagers, it’s so nice to hold it in landscape when reading in a lounge chair!
If you are an engineer or write code or do lots of other things? Then an iPad can be a really nice secondarily device. Or not.
