New times
Last time I were stucked with the idea of using color LCD, and since I am not able to produce a PCB and solder it, I didn't went further. Now I changed my ideas, mainly because now I see people "aligned" with me (or me with them ?).
1st. People need to share art, and in NY people is creating "networks" of sharing using cheap USB flash drives -- I always wanted a device to play music and easily share the art files;
Some artist, like Binärpilot, which I love, says about their art/music files: "share them with your friends, give copies of them to strangers"
2nd. Online shops like www.Etsy.com have users/clients that buys handmade electronics and art pieces.
DIYers are growing and people likes a lot electronics and art, the example of 3D printing robots like RepRap and MakerBot.
My plan is now to continue use IMX233 ARM9 board @ 454MHz:
and wire to it a few buttons + battery + cheap b/w LCD. Then design and 3D print the plastic enclosure. Finally sell it on www.Etsy.com, running Rockbox and including Rockbox source files plus all others like schematics, board and 3D design of enclosure. Also full on music with Creative Commons licenses like this album from Binärpilot:

That board were done to be a general board for Linux and so have all that things. As for Rockbox, I just need as minimum at working the SDCard, LCD, buttons and output audio DAC -- so I will port Rockbox for that.

Cheap (6€ including shipping on Ebay) Nokia 84X48 b/w LCD -- because it's cheap, easy to source and mainly because it's very easy to solder the few wires.
I have "good" color LCD but I can't put it working because of a missing electronics board. I need to move on, so for now I will use that "crap" LCD BUT what I am looking for is audio and not image/video.

Ok Guys,
with respect, I don't ever post here just follow this thread. But, this conversation has perked my funny bone. Rockbox is fantastic to start out with. The guys on this thread are doing an amazing job developing an open source piece of hardware that will run Rock Box and be a great music player. If network support is so important lets all go over to the Rockbox Android forum and have this conversation.
Thanks for all the hard work being done here ..... its looking amaizing

quick question ....... whats the quality of the D to A on this thing as it stands now. Has there been discussion on making this things sound output be better than any of the current store bought players ..... ( HiFiMan) ?

The ARM9 IMX233 SoC have it's own internal DAC, it's a cheap and simple solution however I don't know if it's good or not -- but it should be, I hope. Being OpenHardware the board and having expansion header, should be easy to add an external DAC and components for better audio quality (if someone wants to) :)
