"The launch of BlackBerry 10 has failed to halt the company&amp;#039;s stock market decline, with shares down 6.7% to $12.86 in morning trading. BlackBerry has lost a quarter of its market value over the last four days, despite its new BlackBerry Z10 and Q10 smartphones receiving a positive reception in the media, CNET reports.  Reports suggest that some investors believe the BlackBerry 10 operating system has come along too late to seize significant market share from iOS and Android, while others have expressed disappointment that the new devices will not be available in the US until March and April. &amp;quot;While we were impressed with the features of the new OS, we believe RIM has only closed the gap with more mature smartphone OS platforms and offered limited differentiating services or features to win back customers from more mature ecosystems,&amp;quot; said Canaccord Genuity analyst Michael Walkley. BlackBerry, formerly known as Research in Motion, is expected to endure a tough fiscal quarter with costly marketing campaigns planned to promote its new operating system and smartphones. The high-end Z10 was released in several markets today (January 31), including the UK, but the physical keyboard-touting Q10 is yet to be given a firm release date.
