Toshiba does Acer $100 better, offering the Z835, a Best Buy exclusive, for $800. Its low price is matched by its light weight. At two pounds, 6.6 ounces, it beats all the others here by a good half-pound. But the Z835 also looks and feels the cheapest of the bunch. Its construction seems less solid—particularly the lid, which has a disconcerting amount of flex.
