I think apple are doing fine, everyone needs to stop comparing Tim to Steve, Tim is bringing more of the "Other guys" to the front.
I think the latest re shuffle speaks volumes about how quickly the company responds to non performance, look at Kodak and RIM, they still have the same people on the deck of the sinking ship!
iMac production, yep it's a pain in the ass, but now and again, suppliers let you down.
Siri and Maps, well Siri I'm ok with, Maps were launched 12 months too early, but the guy who's responsibility it was has now gone, and lets be honest it's not atypical for apple to launch a product to a deadline... That was true Steve style!
The iTunes delay gives me hope... Delaying a product launch and openly saying we need more time to get more of it right is better than Launching and patching problems... Windows 8 anyone!?
iToy production issues... It's headlines, I'm sure Apple could launch with a lot more stock than they do, but its a marketing exercise, not a production issue, besides, as far as apple are concerned its a supplier issue, the production issues are for the supplier to deal with!
I think things are starting to level off, Apple had a run at the Tablet market and the Phone market, so we may see its % decrease over the next few iterations, but who knows what hey have up their sleeves!
