We heard in October of last year that the second iteration of PlayBook software had been delayed until February, which is next month, but it looks like RIM was somehow able to expedite the process to get the OS update out the door.
Since the original reason for the delay was that RIM wanted to polish up the software so it "fully met the expectations" of its customers, you can safely assume that everything and anything that was going to be added in the update has been, and it's working quite well.
One of those features is the completed Android emulator, which enables the PlayBook to run Android apps without having to run Android itself. That should make for a more appealing tablet overall, especially since the manufacturer recently cut the price for all refurbished models of the tablet to a mere $299.[Engadget]
