<A HREF="http://www.cio.com/article/124552/Lenovo_Retakes_No._Spot_from_Acer_in_Q_Rankings">Lenovo Group reclaimed the number-three spot</A> among PC vendors during the second quarter, pushing rival Acer back into fourth place. But Acer's exceptionally fast growth means the company is likely to overtake Lenovo as number three for the entire year, if current trends continue.

Acer has been on a roll in recent quarters, grabbing market share and putting pressure on Lenovo. During the first quarter of 2007, Acer tied Lenovo for third place, with both companies reporting shipments of nearly 4 million PCs, giving each company 6.7 percent of the market, according to IDC.
