Blackberry's time has passed, as will the iPhone's: such is the way

You'll have seen the news about BlackBerry---the once undisputed champion in communications technology---essentially putting itself up for sale this week, and may be lamenting the decline of a tech giant. But dry your tears. Such deaths are commonplace in this area of technology. Just as the iPhone muscled in and usurped a device so popular it was dubbed the Crackberry, another player---Samsung in combination with Google/Android operating system---might take down the Apple offering. For every tech company or innovation on the way up, another market leader seems destined for irrelevance.
