Well, as a patent attorney, I don't share your world view of patents.
:-) But on the question of whether a claim to a speedometer using a
microprocessor is similar to a claim to displaying an object list, I'd
say the method claims might look quite similar, but the apparatus claims
(in particular the non means-plus-function claims) much less so.
It isn't really meaningful IMO to say something is or is not a "software
patent."
