I have an old Nokia N95 8gb sitting here doing nothing, do you think it's worth the effort to try and go as far as hard wiring the CPU up to the bredboard and start experimenting with some kind of mini computer 300mhz ARM processors, the newer phones now are coming out with 1.2gig dual cores along with some pretty powerful GPU's enough to run everything i could ever need, but there must be pins out to graphic etc, turning an old smartphone into a computer which can then run Linux (risc os 5 for eg) ? would it be worth the time.....
