Jay Rosen has it right. Finally, somebody gets it.
“Reports of my death have been greatly exaggerated…” is the more familiar line, and it’s funnier, even though Twain didn’t say it.
Interestingly enough, while Twain didn't say this exact quote, it was the one that Jobs' used in his first keynote back from his medical leave of absence. Not only does this douchebag Daisey present the misquote, but he exhibits the audacity to use the borrowed quote from a man whose empire he's doing his damnedest to destroy. Regarding reports in the media about Daisey, Rosen says further:
He doesn’t think it matters whether there actually were such reports. The audience will get it: he’s not going to hide in some cave! He will go on. Yes. And so will his con.
I couldn't have said it better myself.
