In what way does MonoTouch clearly contribute to the user experience on the platform? An argument I started contemplating after reading the article is that there are a lot of non-iPhones out there with a physical keyboard, for instance. I can imagine someone writing for another platform experience makes concessions in creating apps that work flawlessly in a touchscreen-only environment, in much the same way some people might have been tempted writing CLI-apps for the original Mac had it provided one. Granted, most new phones seem to focus on the touch screen, but I can imagine there are other similar differences that might affect how native an app feels on the iPhone platform. After all, it seems that there are iPhone app developers moving to the Mac that create iPhone-like interfaces that don't quite feel at home on the Mac. If there are subtle but noticeable differences between Mac OS X and iPhone OS, I can imagine there are more than a few such subtle differences between the iPhone feel and the feel on other platforms.
