The Galaxy Tab 10.1 will be shipping with Android 3.1 (codenamed Honeycomb) out-of-the-box, meaning you won't have to deal with the hassle of upgrading the OS yourself. The Galaxy Tab 8.9, which still doesn't have a release date, will likely follow in its bigger brother's footsteps too.
@blayze04 you are correct. Galaxy Tab 10.1 original was 3.0 but now it will be Android 3.1 - https://ow.ly/51E07
The WiFi version of the 10.1 will arrive on June 8, 2011 in 16GB ($500) and 32GB ($600) flavors while the 8.9 will also be available in 16GB ($470) and 32GB ($570) versions. They join the original 7-inch Galaxy Tab, which has already been quite a success for the company and has received an upgrade: to Android 2.3.
The hardware giant is touting the two new devices as the world's thinnest mobile tablets, at just 8.6 millimeters thick. The Galaxy Tab 10.1 weighs 595 grams while the Galaxy Tab 8.9 weighs 470 grams. Both support HSPA+ network speeds of up to 21Mbps, Bluetooth, and Wi-Fi 802.11 a/b/g/n connectivity. They also feature a 3 megapixel rear camera and a 2 megapixel front camera, providing seamless 1080p HD video. The two devices are powered by a 1GHz dual core application processor and both feature a 1280 x 800 resolution WXGA display.
What the specs don't mention is that the two devices are preloaded with Readers Hub and Music Hub giving consumers instant access to more than 2.2 million books, 2,000 newspaper (49 languages), 2,300 magazines (22 languages), and 13 million songs. The devices are also designed with Samsung's Social Hub, which will aggregate email, instant messaging, contacts, calendar, and social network connections into a single interface.
