It frustrates me a bit when you see these announcements for a productivity app on iOS, and I'll just sit there thinking "wow, this is almost as cool as the stuff I had on Windows 98...". Stuff like Excel have (historically) been substantially worse than their desktop counterparts on mobile.
Now, in some ways I do understand why this is; I suspect the people making the apps figure that if you're doing "real" work, you'll probably still defer to a "real" computer running Windows or macOS or Linux, but that sort of implies that smartphones aren't "real" computers.
My iPhone 12 Pro is so much more powerful than a typical Windows 98 computer that I'm not even sure how you'd quantify it [1], but if I had to actually do work, it's not immediately obvious to me that the iPhone would actually be the superior option. Microsoft Office 98 is still pretty usable, early Photoshop is primitive but still reasonably intuitive, it's not hard to get proper text editors.
[1] Obviously you can look at clock speeds and "flops per second" and stuff like that, but there's other ways that modern computers are more powerful that are less obvious, like custom decoder/neural chips, better compilers and more efficient operating systems, etc. I think the safest thing to say is it's a lot more powerful.
