I love to see when a company understands that giving something away they will get ten times more in return. And nowadays that happens too rarely.
For a while it seemed that Nokia is about to lose to its competitors, because of Symbian and bad software. This will totally remedy it. I've also heard from Nokia insiders that they're actively dumping everything related to Symbian. It won't take more than couple of years and all their phones use Qt.
Seeing how well Apple has been selling iPhone applications, I can only imagine the potential Qt phones have in future. With Symbian that just wasn't possible, it was a total nightmare for the developers.
