Why Apple Did Release Safari 3 so Early?

For sure Steve Jobs shad the IT world when announcing Safari 3 for Mac and PC with his famous "One more thing". If the announcement created a huge buzz, it might have a strong impact on Apple's image when considering reported experience with Safari 3.
Indeed, on Windows, Safari 3 is indeed fast, but particularly unstable, especially when installed on a non-US system. Many pages are not visible, even for some of the most popular websites.
On Mac, if we do not experience problems linked to the localization of the OS, Safari 3 is only available in English, something a bit weird for an Apple-branded application. Numerous used have reported problems with the Mac version too, including stability issue and data corruption... In some cases, this was linked to compatibility issues with other applications, but not always.
We can not believe that Apple's engineers did not test Safari 3 internally (at least US, Europe, Asia) to provide a better worldwide feedback concerning stability and compatibility issues. Maybe Apple being so paranoiac, to preserve its "coup", did not spread the application outside from its Californian labs? It looks like the decision to release the beta version of Safari 3 was taken without really taking into account opinions from developers; if so, then they are probably in trouble today for having not tested their application in some basic conditions.
Apple will have to work hard to turn back the negative opinion drawn within 24 hours in the PC world. A more advanced and stable version of Safari 3 could have been released and announced in September during the Apple Expo, and would have been the impact on the IT world, with more positive attentions for sure. For iTunes on PC, Apple was able to release a robust version, which with time became popular on Windows computers.
Of course Apple might have suffered from the user experience with some applications, announced as beta version but fully stable, and finalized (such as Google and its apps). Of course in the developer world, a beta version defined an on-going project with bugs and stability issue, with 6 security flaws already identified in Safari 3, Mac users should go back to the 2nd version, and Apple needs to spend more time on the third version before end users can adopt it.
