First of all, while I do look forward to some of the bug fixes in PR1.2, it is not even a minor version - it is a major one, coming with Qt 4.6 and application development compatibility with MeeGo and Symbian 3. This will change everything for our beloved N900. It will give us Shazam, it might give ppl things like separate Skype app (I love the integrated one), it will multiply the available apps for Maemo 5.
Second, there is a huge difference between preloading a firmware in the factory and making it available for seamless OTA update. (Update being the crucial one - like not destroying your existing data and apps, right?).
