I'm not a Mac fanatic, I'm not a worshipper of all things Steve, I don't use any of Apple's products on a daily basis (though I work with a bunch of people who do).
And despite this, his contributions shape and influence my life every day. The WIMP interface, proportional fonts, WindowMaker (derived from NeXT), much of the Web (as others noted, Macs dominate both graphic design and much Web development), music, electronic books and media, movies, and probably a bunch of stuff I'm forgetting.
Look around you right now. Wherever it is you happen to be right now. Every human artifact in your presence was designed, marketed, and manufactured by someone. Every idea in your books, video, or music collections. The scientific concepts behind your electricity, plumbing, and communications. The artistic concepts behind literature and (again) music.
Some people's influence truly outshines the ordinary, and some of these people are even recognized for it. Occasionally you'll be fortunate enough to share time on the planet with such a mind.
Sure, they might be assholes in person or have other flaws, but their contributions are still real and recognizable.
We've lost a genius, a visionary, a creative force, and someone who's touched billions of lives.
As I said: I'm hardly among Steve's biggest fans. But I recognize his greatness and mourn his passing.
Maybe someday you'll understand. I hope so for your sake.
