siliconbits writes "Today, at the BlackBerry Developers Conference in San Francisco, company President and co-CEO Mike Lazaridis kicked off the event with the widely-anticipated news that RIM is developing a tablet PC of its own. Called the BlackBerry Playbook, the device is a 'Flash-loving,' 'device-paring,' 'enterprise ready' tablet, says RIM, with a 7-inch screen. It is 9.7 millimeters thick and features a 1024x600 widescreen display. It also supports 1080p through HDMI and has a USB port." The tablet will run on a dual-core, 1GHz CPU and have 1GB RAM. Its browser will be WebKit-based, and the device will be running a brand new operating system developed by QNX software. The tablet won't have 3G access of its own when it launches, but will be able to tether to existing BlackBerry devices via Bluetooth.
