Of Americans planning to buy high-tech electronics during the holidays, most are picking the iPad or some other form of media tablet, says Retrevo. The shopping and review site recently conducted an online survey of over 1,000 people, which it says points to people spending 16 percent more on electronics this holiday period over 2009. After tablets, notebooks were the next most sought-after gadgets in the survey group, followed by non-3D TVs.
