Early owners of the new iPad are noticeably happier with it than its year-old predecessor, ChangeWave found in a small-scale ownership survey. In the group of 200 buyers, 82 percent were "very satisfied," a sharp boost from 74 percent a year ago with the iPad 2. Another 16 percent were at least "somewhat satisfied" versus 23 percent last year, showing that Apple had tackled some of the complaints of the previous generation.
