That's the benefit of building and protecting a strong brand. HTC for example may sell one specific model of Android device with a camera but who knows it even exists? They don't advertise. They have dozens of different models that look very similar. This makes it difficult for consumers to identify a feature they want, identify the model of device it's available on, and obtain it. Apple traditionally rips down a lot of those barriers by offering a simple, heavily advertised, product line that is easy to obtain.
