A new poll released by Pew confirms what everyone suspected: tablet sales are soaring. The poll found that 19% of U.S. adults own a tablet computer, with the number of those owning a tablet nearly doubling between mid-December and early January — from 10% to 19%. Ebook ownership also increased from 10 to 19%. Pew said that this rise is especially striking, given that it followed a period in which there wasn't much change. They attributed the rise to holiday gift-giving, and the release of tablet computers by Amazon and Barnes & Noble.
