A bad news for all BlackBerry lovers and specially for Playbook fans. Now BlackBerry is not going to update its PlayBook tablets with BB10 OS. RIM CEO, Thorsten Heins, has taken back his earlier decision to upgrade BlackBerry PlayBook tablets with its latest mobile operating system of BlackBerry 10. Heins has made this announcement today at event of revealing first quarter earnings report of RIM. The specific reasons for the decisions are though not being told, yet there are some concerns of performance and user experience. Also the company's earnings are getting downwards, so investors might not have plans to prolong this struggling device. So it looks like the current model will be the last of PlayBook family as Engadget mentioned too.
