At least a GUI solution to convert my MPC files to mp3 for full iTunes/iPhone support.

Very easy to use, it works great on my Quad Hackintosh. There is indeed a freeze when you drop the files on the All2Mp3 window, but it resumes after a few seconds and the conversion is flawless.

For my needs, it's the best tool out there, the other solutions are from bad programmers trying to rip off money from unaware users by proposing expensive and ugly solutions for a problem solved with open source tools a long time ago !
