In terms of interface, the OS looks like a mashup of webOS and the BlackBerry OS, even allowing for multitasking via what amounts to a "card" view. Interestingly, RIM and QNX boasted of the PlayBook's multimedia and gaming functions, but Mike Lazaridis also described the tablet as "an amplified view of what's already on your BlackBerry." That's due largely in part to a function of the tablet which allows you to siphon data off of your BlackBerry handset via Bluetooth tethering and display it on your PlayBook (a la the ill-fated Palm Foleo). While the PlayBook doesn't seem to rely on phone content alone, the press release from the company says that users can "use their tablet and smartphone interchangeably without worrying about syncing or duplicating data." RIM didn't hand out any solid launch dates beyond "early 2011," and of course, there was no mention of retail price. We've got a slew of content after the break, including the PlayBook spec rundown, the company's press release, and a full video of the device (and UI) in action -- so take a look!
