Microsoft has plenty of partners to compete with the iMac. Now those partners can look into the Surface Studio as something to aspire to.
Not refuting your implication necessarily, but worth knowing their flagship (standard and high-end) devices have been 3:2.
Most games and movies are widescreen these days, and I see those as consumery activities. I think a significant amount of consumers would be annoyed by letterboxing in those use cases.
All the creative people I know said Cintiq set the bar, looks like MS is making a square aim at that market.
some artists just absolutely cannot get used to it and so moving off to surface is not something they can do yet.
that's just the value prop of cintiq. the display may be crap but the drawing experience is by far and away the best in its class.
This really just shows you what a bargain the 5K iMac is.

*Surface Dial included
edit: as pointed out below you do get a Surafce Dial with the purchase of the studio. I originally looked at the "what's included" section where the dial was not listed.
