Samsung has just unveiled officially the new Galaxy Tab 8.9 model during CTIA 2011, that took off today. The product fits right between the first Galaxy Tab and the 10 inch model called Galaxy Tab 10.1, unveiled last month at MWC 2011.

The Galaxy Tab 8.9 is now the thinnest tablet on the market, at a mere 8.6mm, even thinner than the 8.8mm iPad 2. The slate only weighs 470 grams, once again less than Apple’s latest toy. Samsung’s new Android device supports a 1280 x 800 pixel resolution and relies on a 1GHz dual core CPU. As far as storage is concerned, the device gets 16 or 32GB of storage, also supporting up to 32GB in microSD extra storage.

There’s also a 6000 mAh battery on the specs list, that will provide 10 hours of playback. As far as cameras are concerned, Samsung Galaxy Tab 8.9 comes with a 3MP one at the back and a 2MP front camera, capable of video chat. The rear photo module does 720p recording and moving on to the connectivity, you get WiFi 802.11 a/b/g/n, USB 2.0 and Bluetooth 3.0. Future versions will also have HSPA+ and 4G.

Android 3.0 Honeycomb is the OS of choice, coupled with Samsung’s TouchWix 4.0 UI. Galaxy Tab 8.9 is priced at $469 for the 16GB version, while the 32GB one goes for $569. Expect its debut in stores this summer.
