High hopes for latest Blackberry handset

They were cool, and then they weren't.

Blackberry phones have struggled in recent years but its maker Research In Motion is about to roll out its latest model, the BB 10.

It will compete with Samsung's Galaxy and Apple's iPhone in a very tough market.

Research in Motion and Blackberry currently have just a 2% share of the Asian market.

The BBC asked Melissa Chau, senior research manager for client devices at IDC Asia Pacific, if it stood a chance of competing with its bigger rivals.
