I know this is an old thread, but I would like to toss in my three cents, adjusted for inflation.
I personally run Ubuntu 13.10 in a home-built quad core gaming rig, which used to run Windows 7 Ultimate x64. I reformatted and installed Ubuntu about eight months ago, and I haven't looked back since. I use a Razer Lycosa backlit keyboard with a matching Razer Imperator mouse, and both work flawlessly. I don't use the built in macros on the keyboard, so I can't vouch for that. What I can vouch for, is the backlighting works perfectly, the multimedia keys are flawless, and the anti-ghosting is excellent. I'm an exceptionally fast typer (90-105 wpm) and this baby never flunks out on me. I've had serious issues with Logitech boards dogging out when I'm in "beast mode," typing reports, papers, etc. I don't get that with my Lycosa.
The extra USB port, as well as headphone and mic jacks also work on the back of the keyboard, because they're just extensions/pass throughs from the back of the tower. When you hook up the Lycosa to your PC, you have two USB ports, as well as a mic and headphone jack to plug in as well.
In conclusion, the keyboard works perfectly out of the box for Ubuntu, unless you HAVE to have the macros. I'm pretty sure you can plug it into a Windows machine for configuration, and then plug it back into your linux box to use them, since your macros are stored in the keyboard itself.
The Razer Imperator mouse also works like a dream in Linux. Since it was first used on a windows machine, the DPI settings were already loaded into the mouse's memory. Once plugged into ubuntu, no software was needed because the Imperator is hardware based. The DPI adjusters on the spine of the mouse still work flawlessly, as well as the extra thumb-buttons for back and forward, or whatever you choose to run there. All of the lights work, and I've had absolutely no mishaps on either device.
I hope this helps at least one person out there. If so, my work here is done. :-)

I would advise going with a different mp3 player. A lot of people on the web seem to have issues with making the walkman interact smoothly with audio programs.
If you want that particular mp3 player, here's how to make it work with ubuntu:

Otherwise, I'd recommend a generic used iPod nano/classic/touch. They are almost always perfectly compatible.
Good Luck!
