I was probably thinking more along the lines of a generic poll, not specifically related to this. Certainly, a UI designed by majority vote would be horrific and nobody would be happy with it (well maybe 2 people).

I just keep reading things like "no major problems in testing", which lead me to believe that there were "minor" problems, which is to be expected. I just wonder about the definitions of major and minor.

As an example: a group does a study and determines that pedaling a bicycle backwards is more efficient, producing more power and is better exercise. They have data to back this up. A company decides to produce the bicycle. Testers are hired and instructed how the bicycle works. After using the bicycle for a couple of days, the users agree that it seems to be better exercise and more efficient, a very few have trouble getting the hang of it
(minor problems). The bike goes into production and gets sold at Walmart.

I'd bet that even though the change should be for the better and improve bicycles as we know them, most people would end up returning them the next day, since they don't work as expected (pedaling forward). Over time enthusiasts may begin pushing it mainstream, but that could be much further down the road.

I guess it seems that it wouldn't take much more to enable some kind of cancel button, or "x" and make both methods work, to ease backward compatibility and allow users the chance to make the shift.
