Squeak,
I doubt that any OS freezes much if you run it as the factory sets it up. It's when you introduce third party software to an O/S that creates incompatabilities. If the O/S is dedicated to the single tack of running ONE kb ... I'd trust that it can do that as well as an internal keyboard O/S.....is there really much difference? All the newer digital gear is computer driven anyway, right?
Who knows?
