I've been using Pocket Player for a good long time now. The Library gesture interface is really coming along well, with every update they fine tune it. I hope to see this type of interaction across the entire program soon.
I haven't been able to get the UPnP stuff to work well, but it looks like it is supposed to stream to and from devices. It might be handy to stream stuff from my Axim to my Xbox 360.
Its been a while since I've used Pocket Player, but I use Winamp daily. To bring down the menu, tap the little square in the upper left corner. Do I get a prize?
Great comparison. Thanks!
