While Apple hasn't really answered this question directly, it has alluded to its quest for perfection being the reason for delay. When it comes to copy and paste, for example, Steve Jobs said that Apple wasn't the first, but that it is the best.
When does the OS get here?
The update will be available this summer. The good news it won't cost you a penny. Though don't get too excited if you're an iPhone 3G user, as you'll get everything else except the multi-tasking capability. Time for an upgrade?
What about developers?
It's all about the application programming interfaces (APIs) and Apple has included more than 1,500 of them as part of the new release. This means developers can start to do even more cool things for the iPhone.
The other good news is Apple has made the beta software and software developer kit (SDK) available for developers straight away. You just need to head to its developer website and get downloading.
