The PlayBook tablet first went on sale in April 2011 running on what BlackBerry then called the BlackBerry Tablet OS, based on QNX. BlackBerry later said it would merge that tablet OS into the BlackBerry 10 OS. BlackBerry also released a major update to the PlayBook tablet OS in February 2012.
The first release of the PlayBook was criticized for not having native email.
