Once the mobile world's pioneers, Nokia, Motorola and BlackBerry are now the industry's sorry laggards, searching for lost glory. As they struggle to get back in a game now lorded over by Samsung and Apple, however, analysts hold out little hope for them. BlackBerry showed off two devices -- the Q20 with its trademark physical keyboard and the budget-priced Z2 with a touchscreen aimed at the Indonesian market -- to help it try to claw back market share.The two BlackBerry smartphones were the first to be produced under a five-year partnership with Foxconn, the Taiwanese manufacturer that is also a key supplier to a major rival, Apple. BlackBerry aims to target corporate customers. "Our turnaround strategy is to focus on enterprise," Chen said. "We are always known as the number one in security." Analysts were pessimistic about his chances. "BlackBerry; that is a lost cause, I think," said Nordstrom. Lawrence Lundy, analyst at Frost & Sullivan, agreed. "They have tried so many things in past years and nothing has worked. I can't see BlackBerry maintaining a device presence much longer," Lundy added.
