I thought about this for a minute. The problem is that, first of all, arrogance doesn't imply ignorance. Data is data: If you believe that an SDK is unnecessary, but the customer feedback data says otherwise, the smart thing to do is to change your mind. Secondly, I see no evidence whatsoever that Apple "did a 180 degree turn" on the SDK. The plan of waiting over a year to release the SDK is working out great. There are good reasons to have done so -- it strings the hype cycle along (if Apple had released everything at once, what do they do for an encore?), it lets the UI designers get some real-world experience, it shakes out the hardware, etc. Embracing MS is also something Apple has done for years -- MS software is a cornerstone of the Mac's success (Excel was a Mac app first!) Finally, it's a mistake to equate the actions of 37s, or the Rails community, or Apple with the actions of individuals. No one person runs these things. Even a tiny company like 37s has more than one person, and Apple is a huge company with lots and lots of smart people.
