Open Source Media player?

I get tired of things like Zune coming out that are great hardware but then fall down on the software. In Open source software, you can write it to do whatever you want and share it. So, I wish there was a way to make an open source portable media player.

I'm not sure exactly how it could be implemented but imagine if you will being able to buy components that sort of snap together without the need for soldering. A screen, a hard drive, some sort of programable chips, whatever. (Duh, in case you haven't figured it out I'm not an electronics guy.) Or go to a website and order I want this screen with these components etc. Pay for it and a company/geek builds it and ships it to you.

Then use some tiny distro of Linux to run it. Would it be as sleek and tiny as an IPod? No. However, with your own hardware and software you wouldn't be screwed by politicians and money grubbing business people.

Ah well. Pipe dreams....
