Leaked "Kin" Product Testing Videos

Wired:

In this first video, testers are giving open-ended, overall feedback in their own words. It’s not good. As one product tester notes, “It’s frustrating, I can imagine my daughter would give this back very quickly.“

Watch the videos — I have no clue how anyone thought this OS was ready to ship.

Also, why did Microsoft need product testers to tell them about these issues? Surely, the people actually coding the OS could see that there were endemic performance problems.
