Strong disagree. I gave up my Macbook for an iPad + (Mini + Jump). I do a fair amount of penciling and consumption, but most of my time is booping around in the window environment with the Magic Keyboard case. Emails, YouTube, WhatsApp, Obsidian, Remoting into more capable machines, sometimes I touch the screen, most times I'm using the trackpad or a mouse.
You're one of the (relatively) few who found the iPad useful for getting actual work done. There are others like you, just not that many. (I tried and failed to make the iPad + Magic Keyboard my only machine.)
