The launch of a wave of Android-based tablets has so far done little to cut into the iPad's share, Nielsen found in a new study. Apple had a combined 82 percent share of US tablets at the start of the spring split almost evenly between 3G and Wi-Fi models. The newcomer Motorola Xoom had two percent, but even established Android tablets like the Dell Streak and Samsung Galaxy Tab had just three and four percent respectively, the study said.
