Sales of the new iPad are up as much as 80 percent over last year's launch of the iPad 2, sources at one of the larger retail outlets for Apple gear in the UK have told Pocket-Lint. One PC World outlet in London, which opened its doors at midnight for a special first-day sale, says it sold a new iPad every 20 seconds for the entire 90 minutes it was open for the sale. Currys, owned by the same company, also reported 80 percent higher sales.
