So... I've been waiting for KDE 4 for quite some time, just reading all I can about it and trying to absorb everything. Unfortunately, now that its out, I have nothing to install it on (my computer's across the country) so I can't try it out.
Regardless, one of the things that I thought was interesting when reading an article about KDE4 was how they found a way to streamline system calls for media (Phonon), but I didn't understand, really, what Phonon does, what it is, and how it solves a lot of media playback issues in Linux.
If anyone could help me better understand, that'd be great, read the Wiki entry and all ;)
