Research wanted! --Another post about labels and hints inside text inputs

This is a bit of a set of reposts about text (whether hints or labels) inside inputs.

However under step4 of Survival Stategy, she asks if anyone is willing to do research (A/B) to see if there is clear form-abandonment between conventional forms and forms using lables and/or placeholders/hints inside the inputs.

Any takers? I would love to either see research back this up, or research show this is a false idea. Research research++
