You make it sound like Google's suddenly found themselves in these unfortunate circumstances through no fault of their own.
On the contrary, this is the reality of Android. You don't get to own the pluses of being "open" and not own the minuses.
Actually you can, you wouldn't blame Linus because your linux based router comes with a broken or old version of linux.
The inability to run a handful of hardware dependent features on iOS is not even in the same ballpark as the complete lack of timely updates for over 95% of Android users.

However, I do agree that Google needs to sort the 'update problem'.
It's one thing to "work" in the hacking sense, and another to "work properly" in the Apple sense.

There's a difference between running and running as well as on the 4S. The demo of noise reduction is impressive. http://www.audience.com/demos/transmit-noise-en.php [audience.com] It's easy to see why with that noise reduction, Siri would be much more accurate than without it, in real scenarios.
Apple obviously wants Siri to be judged on it's best performance. They have a reputation for quality to maintain.
