Today at the BlackBerry Developer's Conference in San Francisco, Research in Motion President and co-CEO Mike Lazaridis kicked off the event with the widely-anticipated news: a tablet PC of its own.

Called the BlackBerry Playbook. the device is a a "Flash-loving," "device-pairing," "enterprise-ready" tablet with an "uncompromised browsing experience" on a 7-inch screen. It is 9.7 millimeters thick and features a high-res wide screen display that supports 1080p with HDMI and USB ports.

In addition, the company announced the BlackBerry Tablet OS, which will power the Playbook. The OS is built on the QNX Neutrino architecture, which the company touts as one of the most "reliable, secure and robust" architectures.

Lazaridis said it wont require new data plans, new security or anything new. It comes with out-of-the-box compatibility. He said it will become the enterprise standard.

It sounds like a powerful device and, as such, it would probably need a powerful battery, right? The company talked up a lot of the specs and the performance but not once - not in the on-stage presentation nor in the press release - was there a mention of battery life.
