I honestly have to say that i can not understand why some people/users are in such hurry? The best way to develop a project / a business / an idea, is to work smooth and to be deliberate. This would have the best success, and not any updates a week with doubtful changes or things that we do not need.
tb 1.0.8 is a good and stable system, which you can use for a productive shop and business, maybe it is a little bit more stable than 1.1.0 (in some things), but this you have try for your own.
Sometimes i think about the future of the project (i already did not use tb productive, as we are not finished with some things), but even if there were disruptions or the termination of the project, we would still have a stable system that we could use for many more months until you switch to a different shop system.
