I think that is a really significant bug and I hope it will be solved in a short time. Is not an usual situation, we are not waiting for a new feature, or more battery life. We are waiting for USING the product we bought. I would say it's a critical situation.
still don't think we will see a 2.0.1 the same week that 2.0 is released. it will take some time to fix this critical bug.
