I Should be clear, i am now using Android and I am very happy with it. the ability to sideload gave me Swype beta which is not afforded through the android market.
If the service provider chooses to block sideloading on android, then they diminish the quality of the device. if the device has disabled sideloading by design by Apple, then it is also diminished in quality, to claim that restrictions made by one are preferable to the other just doesn't make any sense to me.
Apple surely had a great effect on the quality of manufactured devices as well as the range of offering, but i doubt that they had much of an effect on the openness of said devices.
If i understand the article, then the gist of it is that the quality of Android is stymied by service providers, that is true, but it is also true that you can compare apples to apples here, that is, which network provides me the best android experience, and that is a competitive advantage, there is no such option for the Iphone.
Put simply, let the service provider who offers the best most open and reliable experience win. Somehow there is this idea gaining audience, that the Android's "openess" is actually detrimental to it advancement, i just dont see how that can be true on the long run.
Right now, because we are stuck with oligopoly of cellular providers, there is little choice, this will not change until more service providers enter this field.
The statement above "Apple is going to exert the power to control the carriers. Apple is about the only company that can, or will, exert this kind of power" is naive.
Apple has no such power, quite the contrary, it is locked to a single US service provider that doesn't give their clients the best quality of service, consumers that are on AT&T that dont have the iphone dont seem to flock en mass to get one, and consumers on other networks, dont seem to migrate en mass to AT&T just to get it, so the market for Iphone in the US is increasingly limited.
A game of chicken of sorts, we will see who blinks first. The service providers limit access to device hardware in their stores the same manner that apple limits access to software on its online store, it is the practice rather then the practitioner that is at fault here.
