Tablet computers running Google Inc.’s Android will start taking sales from Apple Inc.’s iPad this holiday season and may surpass it in a few years as device makers adopt the software for a slew of models, analysts said in a Bloomberg report. Samsung Electronics Co. showed the newest Android-based tablet for the U.S. market at an event in New York today. AT&T Inc., Verizon Wireless, Sprint Nextel Corp. and T-Mobile all have agreed to sell the Galaxy Tab, Samsung said today in a statement. The device will be available in time for the holidays, carriers said. Smartphones running Android have already surpassed Apple’s iPhone in the U.S., according to researcher Gartner Inc. Google may repeat its success with tablets because its operating system is freely available to any company, said Ed Moran, director of insights at Deloitte Services LP. “There are a whole slew of factors behind the success: the open-source nature of it, the lower price, it’s not proprietary to one company,” Moran said in an interview. “Will that port over to the tablet? I don’t see why not.” Dell Inc., Acer Inc. and LG Electronics Inc. have said they will make Android tablets.
