Except I doubt it was a compromise. They chose to make it square because it fit what they were going for. You’re saying it should be circle because that’s what watches are like, assuming this isn’t just called a watch while mainly being a little computer on your wrist.
Being a watch is nowhere near the primary function.
Apple named that the Apple Watch. That was a conscious naming decision. Semantics much? Should have been named instead: Apple Wristband, Apple Wrist Computer, ...?
So, the Apple Watch is not really a watch but pretends to look like one... Oke doke. I rather stay with a watch looking like a watch, not a pretend to be.
Next thing we'll have to ask ourselves... What is a Computer? Insert hideous iPad Ad.
