Actually his house, as presented on allaboutstevejobs.com, is very rustic and far away from Apple's clean industrial design. I'm actually surprised to find that kind of home in Palo Alto: I'd expect this in Normandy, not around here :)

From that website too: the last picture of this set http://allaboutstevejobs.com/pics/places/paloalto/paloalto.h... shows that his home office hasn't changed much in many many years based on the huge laptop he's using.
