I had to buy a new device recently, mainly for business use, and had a choice between a MacBook Air, the new MacBook and an IPad Pro. I would have had to buy a keyboard for the iPad Pro. Finished up buying the MacBook, mainly driven by the preference of OS X vs iOS, also due to prejudices towards first generation Apple tablets - I've got a first generation iPad that got left behind by the iOS upgrades that weren't supported, which makes me cautious about being a first adopter. Maybe in a few years time....
