True. Apple used to under-promise and over-deliver. They've been making an awful lot of small (and big), almost careless blunders recently, which has flipped that on its head. That's a bad position to be, because it erodes at your reputation.
That said, they've got a lot of pressure on them. They're the biggest company in the world, and they're more closely watched than any company in history (by people like us, not to mention their competitors!). Creativity demands time and inspiration; it doesn't happen on-demand.
Apple has definitely become a more corporate and a lot sloppier in their results since Steve died. It's not fatal yet, but if it continues Apple are just going to become vulnerable to the same kinds of values that helped it originally - attention to detail, care and quality. For the mean time, Apple have a reputation that will give them enough time to rediscover those virtues.
One example: all of the technological masturbation that goes on with Apple photographing casings and matching glass panels to microns; diamond-cut bevels and the like. A lot of people would point to that and say it shows attention to detail and quality concerns.
But then, the device goes and scratches off its colouring after less than a month of light use. That's not attention to detail. That's not focus; having micron-aligned glass is a useless distraction if the other parts aren't equally as well thought out.
Apple used to make the best all-around products. Some parts weren't as good, some parts were better, and the sum was the best available machine from anyone. They seem to have lost that balance for selecting the things to focus on. I don't agree with their priorities at the product level. I wish I was there to offer a counterpoint.
