Leave SAM Alone? I say do what you want with it. But sorry Simon, I have to disagree that the present SAM is inadequate - it's 5yrs (5ish) old and people haven't just left it on their desk waiting until the day that some hardware mod comes out to make it usable. They've been using it all along. If you need a better serial port to deal with some dodgy equipment then you're probably clever enough to sort it out yourself.
I was looking in the technical manual at the spec of the SAM and it says that the component life is >5yrs - presumably 5yrs is the very worst. What then of SAMs sold after 5 yrs - is their component life >0yrs?!
