Dan,
unusual place for the poll...
I will go #6
They are very useful in my workflow, but incomplete. It was said by management that they will acquire features of regular RT's. That is what I am hoping for. When that day comes, I will change rating to 10.
There are many, many ways how these can be used once completed...and my sincere hope, that it comes within reasonable time frame.

But in simple terms, I use these almost every day, even "as is" smile
