I've seen that TED talk. I agree with what he says, but disagree with his suggested solutions. The solution isn't to deprive customers of choice and trap them in a gilded cage with fewer options.
The solution is to make it easier for people to make choices. Like how Newegg's product search lets you take the thousands of laptops they carry, and quickly narrow it down to the few which are quad core, 15"-15.6", with SSD, and cost $500-$750.
I have a Canon DSLR camera. I use the manual, aperture priority, and shutter priority modes almost exclusively. But when I hand the camera off to someone who doesn't know squat about photography and just wants to take pictures, I put it into "green mode" where the camera does almost everything automatically and acts more like a point and shoot. This is what Android needs - a "green mode" which is super-simplified, but retaining the ability to turn it off and set certain or all features manually if you wish.
That's how you improve customer satisfaction through simplification of choice, not by forcing everyone to use "green mode" like the iPhone does. Part of the reason the iPhone's satisfaction ratings are so high is because Android exists, and tweak-a-holics dissatisfied with the iPhone's limitations have abandoned it to use something else.
