So this setup is for people who use a Mac, but not a Mac laptop (or who keep the laptop closed and use it exclusively with an external monitor), and who also don't want to buy Apple's keyboard with Touch ID, or an Apple Watch. I gotta say, I don't think that's a huge group of people.
Having a mac laptop doesn't help either if you use it primarily as a secondary monitor, relatively far away from your reach. This is a pretty standard setup in enterprise IMHO.
Then not wanting to wear a watch and wishing for a better keyboard than the Apple one don't sound outlandish either.
