Well, the solution is called programming, the PIA is not much more

With open source code doing that is made much easier, if someone hasn't
already.
I work with embedded hardware/software and often the IO reduces to USB
or TWI interfaces
that are already known. Since much of the ARM based hardware already
runs linux the next
steps are pretty easy to get to.
In the end don't tell me about it, as Yoda might say; Do or not do, no
whine.

Hard to say. Embedded tasks to me require lots of I/O and that seems

That "low price is best trend" I would change. For me a modern
programing tool is "text editor" and 80x24 text screen on 15" display.
Explain to me why a cheap PC in my home can't keep up to the net
(windows 7) and a credit card computer can do better for surfing.
Ben.
Simple task specialization, and task overhead limiting. That and in7 is
just a bigger pig.
The average PC has many tasks running and even then unless the CPU is a
pig and the graphics
unassisted doing a web browse is usually limited to only how fast all
the data gets there.
However for 80x24 text terminal the cpu overhead is very low and the
graphics load (screen)
lower, linux give you that if you don't run the GUI and its very fast. I
know this from running
and ARM7 based system at 300mhz and for text and compiling code for
itself the limiting factor
is actually the disk subystem (a micro SD chip).
To e the raspberry-pi is a great computing resource for embedded tasks.
