Well I spent the train journey to work this morning watching TNA on my c7x0 using Xv under X11.
This is due to “sirfred” and his amazing new xserver for the imageon chips, http://www.openembedded.org/filebrowser/org.openembedded.dev/packages/xorg-xserver
I think this makes the c7x0 currently the coolest zaurus about.
