Microsoft has an absolutely terrible track record in the creative productivity category to the point that their previous entrants fell somewhere between “toy” and “joke.” I don’t have high hopes here, personally.
I would wager MS Paint has done more to spark creativity and set people on a path to becoming digital artists than any other piece of software in history like Photoshop. I wouldn't underestimate the power of 'toy' programs.
Not sure how that's relevant in this context but maybe you're saying designers should just stick with MS Paint instead of this new software?
I think it's more about how playfulness and exploration can be powerful for non-professional users.
I agree, but MS Paint did so because it was available to anyone who opened up Windows, not because it's a great piece of software.
