Well, well, well...isn't this an interesting turn of events? The BlackBerry PlayBook has the potential to become an iPad mini and a Nexus 7 competitor.
The OS upgrade, from PlayBook OS 1.x and/or 2.0 to BlackBerry OS 10 was announced during the BlackBerry 10 launch event last week. (It was also mentioned as far back as March, 2012.)
The BlackBerry PlayBook, originally released in 2011, was suppose to be an iPad "killer." The market disagreed. You can still purchase PlayBooks online and in retail outlets, but it is running it's original OS which, evolutionally speaking, is stuck between BlackBerry OS 7 and the new BlackBerry OS 10. The PlayBook OS was built on the technology acquired from QNX.
I think it's amazing that another company besides Apple is going to reward their customers with a software update that will refresh previous generation hardware. Heck, this might even be the excuse I've been looking for to purchase a refurbished BlackBerry PlayBook and then upgrade it to BlackBerry 10 later on.
