Having read about (and watched videos of) iPadOS, I still get the feeling that this is much ado about a few little tweaks (again, Apple sweating out the details and doing incremental improvements) rather than an actual breakthrough.
I think the main reason for that is that I have a profoundly different take on what “work” means than Federico–like one of my friends said the other day, there is a lot more to the “work” that we do than, say, wrangling Markdown documents, and to this day there is, for instance, no generic web development story for the iPad (very few scripting languages, no way to run anything “normal” locally, etc.), nor a full featured “knowledge worker” setup (you can’t use most professional Office features locally on an iPad, and even corporate e-mail and calendaring is still a pain).
All we really have are cute workarounds, and excellent (but often short-lived) third-party apps that fill some gaps for some of the people, some of the time.
It’s a new start, yes, but still a way off from the status quo.
