Recently, however, Lenovo announced their LaVie Z and LaVie Z 360 ultrabooks and at 1.87 and 2.04 pounds respectively, they're almost ridiculously light. Further, with Core i7 mobile processors and fast SSDs on board, these machines perform impressively well in the benchmarks and real world usage. If you actually pick one up though, both models are so light they feel almost empty, like there's nothing inside. Lenovo achieved this in part by utilizing a magnesium--lithium composite material for the casing of the machines. Though they're incredibly light, the feeling is almost too light, such that they tend to feel a little cheap or flimsy. With a tablet, you come to expect a super thin and light experience and when holding them in one hand, the light weight is an advantage. However, banging on a full-up notebook keyboard deck is a different ball of wax.
