If you look at the spec sheet below you'll see that you're essentially getting the same specs as on the Motorola Xoom, but the weight is significantly reduced by using plastic as the main material at 600 g vs 730 g. The screens are about the same size, but the Samsung Tab features a slightly battery of ~6900 mAh vs 6300 mAh (not confirmed yet). That Samsung device also has an 8 MP shooter on the back instead of 5 MP (not even sure this is at all relevant for a tablet) and the same 2 MP camera on the front.
There's not much to talk about here, really, but as long as Samsung undercuts the Xoom in terms of pricing (last rumor puts the latter at either $800 or $1100, which is unacceptable), I think Sammy has a good product running an unaltered version of Honeycomb. On that note, Samsung promised to keep its paws off the OS and make this a Google experience device, just like the Xoom. Thanks go out to the guys at Engadget for the spec sheet and video below:
