However, since debian is not primarily real-time oriented, it might be a bit difficult to use these pins in the same way as you would use an Arduino. Don't know whether a RT kernel with appropriate drivers will be available. The R-PI has so much more processing power than an Arduino that it should be able to perform mostly the same functions in user level (on a RT kernel, of course). One of the nice things of the R-PI is that it is not tied to any specific operating system, there are already efforts under way to port RiscOS, and given enough determination, other OSes should be doable as well. Although this creates some barrier for sharing software, it can stimulate experimentation, so overall I think it's not bad. I'm seriously contemplating getting one - the unusual situation with this geek toy is that I don't have to convince my wife that it's not too expensive (nobody can argue against a $25 or $35 proce tag) but that I won't spend day and night with this thing after the package arrives :-)
