Acer CEO Gianfranco Lanci in a question and answer session after his tablet unveilings this week said that he hoped to beat Apple in the tablet market within two to three years. He expected Acer to get 10 to 20 percent of the field shortly after launch and to take the lead from the iPad later on. Apple's problem was its US-centric focus, which could hurt it where Acer and others were more world oriented.
