The 7-inch Thrive felt surprisingly lightweight in my hand. When I held the 0.47-inch-thick tablet in one hand, it reminded me of holding a first-generation Kindle e-reader. It was mostly comfortable, but certainly had room to slim down more--of course, stand-alone e-readers have been doing that since their initial introductions.
What struck me was how balanced this tablet felt--lighter than its listed 0.88 pound and comparable to the first-generation 7-inch Galaxy Tab, which weighed 0.86 pound. However, the upcoming Samsung Galaxy Tab 7.7 will weigh even less, at 0.75 pound. So, while the Thrive is light, it's not the last word in tablet weight.
