In the interest of avoiding confusion, Samsung has shied away from calling its second-generation Series 9 computers “ultrabooks” since it didn’t refer to the first generation — which launched last year before Intel birthed the ultrabook moniker – as such. But the new Series 9 looks like a duck, quacks like a duck and pretty handily out-ultrabooks most actual ultrabooks as far as thickness and weight are concerned. There’s bound to be some confusion, in other words.
