RIM enters the tablet game with the Blackberry Playbook - its first device of the sort.
The announcement follows news of rival tablet devices such as Samsung's Android powered Galaxy Pad.
With a 7" screen, dual core processor and dual cameras it's described as a 'professional-grade' tablet aimed at business executives.
A slick video presentation highlights the tablet's strengths against the iPad, including multitasking, tabbed web browsing, and Flash 10 and HTML 5 support. It also shows videoconferencing and business presentation capabilities.
The Playbook supports wi-fi but has to be paired to a Blackberry handheld to access 3G networks.
RIM emphasises the Playbook's security strengths and seamless connection to other Blackberry devices and Enterprise server.
Also highlighed are unbusinesslike features like power as a gaming platform and HD video playback.
The device seems to be an answer to both the iPad and core enterprise market tablets like Cisco's Cius.
RIM commands 3rd place in European smartphone sales after Nokia and Apple.
Its international sales are growing strongly particularly in Asia, while dominating the US smartphone market with 18.2% market share (down from 19%). It faces increasing competition from the iPhone and Android devices from Motorola and HTC.
