Given the choice between doing what you're doing now and doing something better, what would you choose? Certainly I am not deriding the Elementary team for copying OS X. It's definitely 'not cool', but open source since GNU has always been about copying the hard work of others and the net effect in this case is that users get well considered graphic design for free (or $10 I suppose). I'm complicit in that, so we pass over it in silence. But I am trying to show that roughly copying another interface has a certain effect – beyond the inherited good properties of the original design – on the user that is problematic. Differentiating yourself from other products has a purpose beyond 'just being different': avoiding the uncanny valley. In other words, this is constructive criticism. Don't ignore it because it's "negative" and you're doing something "positive". All progressive positive things are born out of a criticism of the existing state of affairs. Any effort can be improved. If you ignore criticism – not just mine – you are doomed to stagnation!
