Wasn't able to be here for a while, so my answer is late:

The intention with the absolute positioning is, as the name says, absolute positioning: without having to skip through the song!

It is very annoying when you want to listen to the last 5 minutes of a 90 minute mix and have to do fast forward just to get to that point.

Imagine the dimmer control in the current beta (or loudness etc). By just using the knob, you'd be able to jump to a certain position very quickly. Also, you have the visuals helping you to jump to the correct position, with a very very fast forward you will most likely miss and have to skip back etc.

Once you have the feature, you know you don't want to miss it. For all those who do not know what I mean, install Winamp and imagine using the slider with the knob.
