Well I would not take the "TS7800 is not embedded " too literally.
Certainly embedded systems are getting more and more powerful so in
some ways the limitations of embedded systems are less than they used
to be.

However, I would take seriously the fact that key hardware elements
depend on closed-source proprietary drives and even the hardware
interface is not fully documented.

That is a show stopper for me.

At least with 7200 series boards the SDcard driver has been developed
into the mainstream kernel if you want to build your own 2.6 kernel.
This would actually be a worthwhile exercise if you want to explore
working with linux on embedded.

Just how "embedded" do you want? The basic idea of running linux (or
some other OS) is that you don't need to do any low-level embedded stuff
since OS takes care of that. If you want to do everything yourself then
try PIC/AVR microcontrollers or don't use operating system.

Yeah... Considering that it has only 128mb ram and no display makes it
";embedded&quot; for the most people. Only the unix gurus who still only use
text mode displays over serial/ethernet think of it as a normal
computer.

That is a really bad thing. Everything would be better if there wouldn't
be proprietary/secret documentation of HW interfaces and protocols.
