1.3 mln Blackberry subscribers in the US

Research In Motion now boasts about 1.3 million BlackBerry subscribers and it signed up 270,000 new users just last quarter, according to USA Today. It's slowly taking market share away from Palm or Pocket PC PDAs as well as laptop makers. Many users say they will sit at their desks and use the BlackBerry for e-mail, while their desktop computer sits idle. Others find the devices indispensable no matter the time of day or their location.
