Whilst I agree that relative position is used in language, I don't think you can associate that with ease of use. If anything, your example of language is a good one to show how relative position makes things so much more difficult (although it gives you more options) to learn/use. And I think empirical evidence lends credibility to the article - everyone gushes how easy the iphone is to use compared to all the other phones out there. One of the biggest reasons would appear to be the 'fixed' layout.
