Personally, I like the "rules" that Apple has put in place. It keeps developers on top of their game and provides end users with a predictable experience. Most consumers want this. Not everyone wants to "hack" their phone or goof around with every widget out there.
I do think Apple could ease up on some policies, but overall, rules keep the platform clean and I use Apple products because I know what I'm getting. I think what is Androids "advantage" today is their hurdle tomorrow.
With that said, they are both good products, but I think the only thing that holds back Apple today is product availability - they even say that in the article. Once the iPhone is available on more carriers and Apple is able to keep up with demand, there numbers will change.
Bottom line though... Android and Apple are good for each other. Each will cause the other to get better. Both will evolve and change. It's those who don't change... or don't change fast enough is who is loosing. Right now MS, RIM, Nokia and others are on the hot seat... they are the ones loosing the Smartphone race. Not Apple... not Google.
