Centrafuse is/was pretty good I think. Well it was back when I was playing with it a year or two ago. It doesn't look like too much has changed since then though.

I see they have 2.0 beta at the moment. Gestures are coming for one.

They have gone and renamed/repackaged it though which would tend to suggest sales weren't great.

I didn't really like the Navigation software they embed. It's "Destinator" (google it). I much prefer my TomTom (on my Nokia E61) but you can't get that for a PC that I'm aware of. It did work though.

Apart from that as a media player it worked reasonably well. It didn't require too much tinkering in terms of general use, but you might have to play a little with resume/hibernate stuff - nothing major though.
