I 100% agree with you. I wrote almost two years ago about how the iPad still had a lot of ground to cover when it comes to productivity. And this was before split view! Even now, after the iPad Pro, there’s still a lot that can’t be done.
I’ve made a huge effort over the past 6–8 months to use my iPad more to get work done; I now take all my class notes in college on an iPad. Like you, the iPad is simultaneously my favorite and least essential device. If I could only have two devices, they’d have to be an iPhone and a Mac. But I love my iPad. Here’s hoping it keeps getting better.
