I go back and forth on the secrecy front. Part of me wishes Apple would be a bit more open with what they're working on just because they need some good PR right now. Google's done that with The Verge, letting them have a sneak peak at Glass and letting them do a feature on UI design at the company. Another part of me says screw it, let the products speak for themselves when they're announced. And I think back to last year and how it was a bit of a letdown just because so many things leaked ahead of time and the keynotes had no real surprises.
I still think Apple does need to do something on the PR front. Every day seems to be an onslaught of negativity. Most of it is not based in reality but often times perception can become reality and that's what I think is happening with Apple right now and part of the reason the stock is in the doldrums. But I see no evidence that Cook or Schiller have any plans to counter any of this negativity.
How do you counter negativity? Not by trying to sooth the media. For them, it's just Apple's turn in the barrel.
Best is to maintain the roadmap and strategy in place, acknowledging the competition, internally anyway, but keeping future products dark to the world.
As for Google Glass, a million years of primate facial muscle evolution says the market is niche. A watch on a wrist, on the other hand, is widely acceptable; still a niche, but at least a large niche.
