So, what does the series of Toshiba Portege Z830s announced Thursday offer that these other Ultrabooks don't? Toshiba claims the Z830 is the lightest 13.3-inch laptop in this class at less than 2.5 pounds.
Toshiba's Z830 announcement states that the company has shaved about 20% of the weight and 40% of the thickness in the laptops from the Portege R830 Series-- which was already pretty svelte--for the Z830.
While the Portege Z830 has a slim 0.63-inch profile, it lacks the unibody design of the Lenovo IdeaPad U300s and is less of an Apple MacBook-Air clone than other Ultrabooks.
Priced at under $US1000
However, you may find a Portege Z830 more attractive just for its sub-$US1000 starting price, that magical price point Intel sold us on for this new class of ultraportable laptops. Toshiba may have managed that low price by sticking a relatively small 128GB SSD in its Ultrabook.
If you can live with the smaller storage capacity and are looking for the (self-proclaimed) lightest 13-incher available, you can pick up the Portege Z830 starting in November.
