Next week, RIM’s first tablet, the BlackBerry PlayBook, will finally go on sale. Before we took the PlayBook to the labs for testing and itsfull review, we unboxed the tablet and played with it, taking photos all along the way, to give you a look at what you’ll get if you buy a PlayBook when it becomes available on April 19th.

At launch, you can buy one of three versions of the tablet, all identical except for varying amounts of built-in storage. All current models are Wi-Fi-only, but 3G and 4G models are on the way. The 16BG model will sell for $499.99, the 32GB for $599.99 and the 64GB for $699.99—the same prices and capacities as the Wi-Fi-only Apple iPad 2.

Included with the PlayBook is a soft carrying pouch. And we also got our hands on optional rubber and leather cases from RIM. None of the cases have magnets or special interactions with the tablet, unlike the Apple iPad Smart Cover, which can wake up the iPad or put it to sleep by simply moving the cover on or off the tablet’s screen. The cases have cutouts for the Volume and Power buttons, and for the front- and back-facing webcams. Pricing has not yet been announced for either case.

The PlayBook runs a new operating system, optimized for tablets, called the BlackBerry Tablet OS. In the past few months, other competitors have redesigned their mobile operating systems to be optimized for tablets as well (like Google’s Android 3.0 and HP’s upcoming WebOS 3.0 for the HP TouchPad.)
