People just rarely use tablets to browse the web or do any general computing.
I think you have a cart-and-horse problem, here. People could do "serious" work on iPads if the software allowed it. I had an iPad pro, and aside from Xcode, and ARM embedded development, I did just about everything on it. Spreadsheets, documents, graphical diagrams, SSH to support remote machines, email, etc. I had a company supplied MacBook, but the iPad did just about everything I needed, and was easier to use, in some cases; like when I had to pull off the highway on my drive home to resolve a ticket because I'm on call, and we had service uptimes to meet.
I'm not seeing how buying an iPad locks people into buying a Mac laptop
For most of my day-to-day use - socials, email, etc - I can easily get by with iOS. I'd be happy to be able to take just one device - an iPad - and do the day-to-day, as well as open up an instance of Xcode to work on projects, too. But even though the underlying hardware is clearly capable of this, I can't; I'm artificially restrained. This is a case where I'm forced - eh, not quite at gun point; maybe more like compelled - to get a MacBook, if I want to be mobile. I know: it's all "first world problems," but Apple isn't helping things by artificially limiting performance, here.
