The BlackBerry PlayBook is a mini tablet computer developed by BlackBerry and made by Quanta Computer, an original design manufacturer (ODM). It was first released for sale on April 19, 2011, in Canada and the United States./
It featured a dual-core 1.5 GHZ processor, 4G LTE and UMTS/HSPA+ cellular connectivity, and an NFC chip. Unlike the earlier PlayBook model, the PlayBook 4G LTE was only sold through carrier channels. In November 2012, another variant of the 1.5 GHZ PlayBook, the PlayBook 3G+, was released in the UK. Unlike the Wi-Fi models, the 4G LTE and 3G+ models are not available in 16 GB or 64 GB versions.
