I'm in the camp of the keyboard accessories make the iPad, well not an IPAD. You might as well have a MacBook then. I think the best use of IPAD's just straight with a case and a slim one at that. If you must have a keyboard, I like bringing my Magic Keyboard and separate trackpad, which I have a case for.
I can readily remove my iPad from the MKB and have a pure tablet form factor with touch screen, not something I can do with a MacBook. For me, that makes it more versatile than a MacBook.
