Confusion over Clipper, Capture, and Clarity

Confusion over Clipper, Capture, and Clarity

I'm really confused by the three products Clipper, Capture, & Clarity.  I don't want to have three different capture tools on my extension bar and I'm really confused as to which one to use (and why there are three different products for almost exactly the same purpose.) And I don't know which one is the "future" product where most development and enhancement is going to be placed.

Can someone explain this to me?  Maybe there is a help document that very clearly compares all the features, why use one over the other, and which one is the "future" product.
