The article's point still stands though: sticking to a platform's design == jarring user experience.
Not to say that I agree that it's necessarily bad: his example of Word on Mac vs. Windows is actually interesting bc, given sufficient differences, users would have a hard time switching between the two if they own both platforms and the applications look completely different. I think it should be possible to retain certain UI paradigms (e.g. back buttons, toolbars) while staying uniform across all platforms in other respects.
