I don't have one but after trying out the iPad with the new apple pencil I can see it being more useful in a lot of situations where drawing is more useful than typing. and having a passable keyboard built into the cover should be sufficient for most people. now if you absolutely can't live without a bluetooth keyboard it might be a bit more cumbersome but the benefits that the pencil bring should outweigh that.
When I’m travelling, I don’t necessarily want “so many more uses.” Being constrained to e-mail and simple editing, together with the iPad’s small form factor and extreme mobility, can be more productive than lugging around a laptop. (I use a laptop most of the time. But depending on one’s workflow, an iPad + Bluetooth keyboard at the hotel room can be a productivity boost.)
