Yeah i looked around with google and didn't find any mother boards for sale yeah a palmtop pc would be all good , thats pretty much what i had in mind with the view towards repairing that and the fact i still have the broken device and the insurance company don't want it so i figured hey why not have a crack at getting it repaired . Id probably consider having a go myself if i could find the right bits . Just seems to be a shame to leave a spotless n900 as a paperweight
