Apple, Lenovo and Toshiba are some of the few computer builders to see their sales go up in a harsh November, the NPD Group said Monday. PC sales in the US were down six percent overall last month, but Apple grew 19 percent, Toshiba 22 percent and Lenovo 69 percent compared to a month earlier. Dell and HP by contrast suffered during the period, as Dell grew just five percent while HP's results plummeted 15 percent.
