I (and others in the office) have. You are right that a bluetooth keyboard does pretty much solve the typing issue, and using the actual Magic Keyboard over the floppy iPad-specific keyboards gets it significantly closer to the feeling people are accustomed to. Definitely necessary if you are going to be working on a document (or replying to an e-mail with more than a sentence), but for myself there was still a huge productivity barrier by having to go from the keyboard to screen for mouse actions (scrolling, selecting text, hitting a button). The keyboard/trackpad combination allows both typing and mouse actions with minimal movement on the same plane. It sounds a bit lazy or silly, but I found having to pick one's hand up and poke something on the screen was pretty disruptive.
