Thorsten Heins, chief executive of BlackBerry, thinks tablets will die soon following the fate of desktop computers. Speaking at the Milken Institute Global Conference in Beverly Hills on Monda, Heins said he believes tablet computers will become obsolete in five years, and as such, BlackBerry has no plans to enter the business again.

"This is your one and only computing power that you will carry with you," said Heins, holding up one of BlackBerry's new smartphones.

Heins added that some of his customers in parts of Africa and Asia, markets he says are responsible for keeping BlackBerry alive, already use smartphones to run micro-businesses.

Heins said BlackBerry has no plans to follow up on the unsuccessful PlayBook tablet it released two years ago. Instead, he said, the company is gunning to be the "absolute leader" in the mobile market within five years.

BlackBerry will keep its focus on the enterprise market and build secure, high-end smartphones that make it easy to type.
