I resemble that remark. I expect Apple to deliver a product that just works. And I admit I enjoy being grumpy.
A product that "just works" does not really exist when it comes to complex devices - it's more of a marketing term explaining how some things are designed well. Apple did deliver a product that is designed well - other than a few iOS constraints (that we all hope will be addressed), iPad Pro is really, really well designed, easy to use and powerful for certain workflows (and of course, not for every workflow). So, if you prefer that term, yeah, you could say "it just works".
Sure, not all people like it and sure there are workflows where you just can't use it. But guess what, there are workflows and requirements where a full laptop is not enough.... there are workflows where a single desktop is not enough.... so what? Do you go around laptop forums saying that you payed 3000 dollars for a laptop and now you don't even have an 12 core CPU like you could on a desktop?
iPad Pro is a great product for certain tasks, and Apple made an ad showing an iPad doing some of these tasks intended for people who need a device for these tasks. Why are so many of you triggered by this?
This is why most people here are "grumpy" (I would use words like "bitter", "envious", etc but ok). And if you enjoy it, well, that certainly makes things easier for you, then
