What about amarok? ( http://amarok.kde.org/ )I find iTunes to be terribly annoying and slow. I also don't have an iPod so... Do you run rockbox on it? ( http://www.rockbox.org/ )

I've found digikam ( http://www.digikam.org/ ) to work pretty well. Never really cared for iPhoto though.

Keynote, again never really used it. I hear it's much nicer than the MS equivalent.

The wife likes GarageBand and it does seem to be a pretty sweet app. Not really sorta thing so I don't really know of any replacement for it. Audacity is the only thing that comes to mind and it's not exactly the same kinna thing.

I hate iTunes, but I've tried and failed to find a usable replacement on Linux. The best I found was Banshee, but the UI's not great and it's quite unstable :(.

I've been on that long journey. I used quod libet for a while, but never much liked it. Now, I use clementine http://www.clementine-player.org/ Best on Linux, imo.

I really liked quodlibet (http://code.google.com/p/quodlibet/) back in the days I only used linux. Don't know if you like the UI though.

My iTunes replacement is a jailbroken iPhone, SSH and dTunes.

there's Ardour (www.ardour.org) to replace GarageBand...

Keynote: This is one of the biggest things i miss in Linux. Hopefully, the Ease project will mature soon. http://www.ease-project.org/
