There is no single platform that can span top-to-bottom hardware and all form factors (some of which stem from software requirements, though). That's a fact. Thus, *some* platform fragmentation is inevitable. We saw already one metaplatform that tried to address this - Java, and it failed miserably, as it was plagued by fragmentation to the level of the original problem it was trying to solve. Now, with Qt, Nokia has the chance to do it right without confining itself to a particular hardware/OS niche.
