Turns out the Galaxy Tab 8.9 & 10.1 are both thinner and lighter than the already impressive iPad 2. Both honeycomb tablets will be the first to stray from the pure Android 3.0 and instead running on what Samsung calls its TouchWiz UX or TouchWiz 4.0.
...Below is a review from engadget:
As you can see from the gallery, both the 10.1 and the 8.9 look extremely similar, and boy are they thin. They measure just .33-inches thick, and as you can glean from this picture, they absolutely give the .34-inch iPad some real competition in terms of dimensions. The models we saw weren't final -- in fact, they didn't even power on -- but Samsung says the 10.1 will weigh 1.31 pounds and the 8.9 just 1.03 pounds. Both tablets have microSD slots, 3.5mm headphone jacks, and SIM slots, although there will be WiFi versions of both of them. The two tablets have the same array of cameras, which includes a 3 megapixel shooter with an LED flash on the back and a 2 megapixel lens on the front.
Internally, the Tabs will pack 1GHz dual-core processors. We're assuming it will be Tegra 2 since all the Honeycomb tablets thus far have used NVIDIA's silicon, but that's unconfirmed at this point. The 8.9 will be available with 16GB of storage and a 6000mAH battery, and the 10.1 will come in both 16GB and 32GB varieties and with a 6860mAH cell. Both are said to provide 10 hours of video playback.
The WiFi 10.1 will hit on June 8th -- the 16GB version will cost you $499 and the 32GB $599. The 8.9 is $469 and $569 for 16GB and 32GB, respectively....check out the hands on demo video below!
