Steve Jobs narrated the first "Think Different" TV commercial (the version that never aired) back in 1997, before Richard Dreyfuss was brought in for the final version. I'm sure many others have or will post this link as well, but it is a great way to remember Steve because back in the Homebrew Computer Club days with Steve and Woz showing off the Apple I, I don't have any videos -- just lots of fond memories of all those times long ago.
We'll all remember Steve, but also must think of his family and their loss. Grief is very difficult, and those who have not experienced a close loss don't have a clue how difficult. My condolences to the family.
