It's a fundamentally different paradigm. A lot of people who have been in the mobile business a while remember the 'bad old days' of J2ME and horrific compatibility problems. Don't forget, a new version of Windows comes around every 3, 4, even 5 years. But on mobile, we have new OS versions dropping every year, at least. And these new versions bring substantial new APIs. So it's a very different environment to a traditional desktop OS.
