My fingers are crossed, but it's way too soon to say there are no bugs. The 900 had to be out for a little while before things started to pop up.
I'm not too concerned however. I THINK Nokia will do everything they can to squash bugs before they release and I KNOW Nokia will go the extra mile to make me happy as a customer if there are any, because that is what they did last time (I got my phone for FREE even though I wasn't affected by any of the bugs)
Every company has new devices that have one bug or another. What's important is how they respond to them, and when it comes to that Nokia does a better job than any electronics company I've ever seen. That is one of the key reasons I will be a repeat customer.
