icloud could affect the distribution of flash memory

As we know, Apple is moving in the interest of data storage in the cloud, which would lower the need for physical storage on our iPhone, iPad, iPod or Mac Using this information, and adding to this that Apple monopolizes currently 30% of the current flash memory market in 2011, Digitimes venture to predict a decline in sales of this type of memory medium / long term.
In my opinion, Apple has the final say despite his intentions, because behind every iPhone is a user, who ultimately decided after much of the history of Apple, buying or not the products of the brand . I say this because I personally am opposed to all my data depend on the security a company can have on their servers, both in reference to the vulnerability to unauthorized access, and the distribution of confidential data and the possible such loss of data due to storage failure. For now I rely on the security itself gives me the physical memory of my terminal and backups as I can manage and control. What do you think about it?
