First up, Arik Hesseldahl of BusinessWeek asks if Apple is ditching Macworld for CES. While many saner minds drafted up lengthy retorts, Daring Fireball nailed the one-punch-kill: "No."
Daring Fireball also gives it's own perspective, that he not busy being born is busy dying: "Traditions are comforting. But comfort, I think, tends not to breed innovation. It can be hard to tell whether you’re staying the course because it’s the right direction, or because you’ve dug yourself into a deep rut."
John Siracusa of Ars Technica suggests Apple's exit from Macworld is part of their "fearless" DNA: "Though painful and jarring in the short term, these kinds of moves are a big part of what makes Apple great. While other companies are paralyzed with indecision, or cling relentlessly to what has worked in the past, or are seduced by sentimentality, Apple is busy murdering its darlings. Though such dramatic moves often appear foolhardy to its more cautious competitors, Apple usually has the last laugh, working through the initial pain to find itself in a much better position down the road—a winning position."
