Courier is dead!! Right or wrong?

I keep reading about how upset everyone is about the courier being killed. I saw the videos and thought they were amazing. But, I totally think they made the right decision. Here's why: 1. battery life 2. weight of the device 3. niche market 4. no correlation with other Microsoft products 5. Price, there is no way this would be priced competively. Anyway, I would be interested to hear what other opinions people have. More to the point, why would this be better than a windows 8 tablet besides the fact that it would be out now?
