For me it's mostly a novelty - I put RiscOS on it to try it out, and it seems snappy enough. But it's a mess of cables - I never got around to making it as pretty as some [1]
Not the person you replied to but I have the same setup. The only real issue is getting the adapters so they can be connected (plenty available on a variety of websites, but of questionable quality).
