TORONTO (AP) -- Research In Motion has released an upgraded operating system for its struggling PlayBook computer tablet almost a year later than it first said it would.
The BlackBerry maker said Tuesday the software allows for built-in email, calendar and contacts on the tablet. When RIM launched the PlayBook last April it said would add the features within 60 days, but later pushed that back to the summer and then to October and finally to February.
The PlayBook received negative reviews because it didn't have those features.
The PlayBook is RIM's first effort to branch out from its smartphone base and capture a portion of the tablet computer market. The tablets however haven't been selling well, forcing the company to sell them at a deep discount.
The update is free to download.
