I use a combo of desktop computers with giant screens and an iPad. I like this better than having a laptop. I don’t think the traditional multi-window paradigm works well on a very small screen (though I am aware it was invented for tiny screens!). When I’m mobile I prefer to have just one app at a time, or at most Stage Manager.

The biggest problems I run into with iPadOS are not related to the OS, but stripped-down apps, or apps that don’t use the file picker and other iPad features. In a few cases I have to use web apps (which work perfectly) instead of iPad apps, for example with Google Docs, since the iPad apps are more like stripped-down phone apps.
