My girlfriend called me at 0650 this morning to tell me.
I'm not surprised, but it is a little sad. Some of Steve Job's concepts of software design have been years ahead of others. Take NeXTStep for instance. A system designed in the mid-late 1980's that almost looks like a modern OS and certainly functions like one. Not forgetting that it was also a Jobs-designed NeXT machine that acted as the first ever web server.
Even with just that as part of his legacy, there would be plenty there to reminisce but it's also remarkable how he essentially single-handedly turned Apple from an 'also-ran' on the verge of bankruptcy to the World's biggest technology firm in just over ten years. Singular and esoteric, apparently very difficult to work with but with a vision and determination.
