Nielsen: Apple’s iPad still commands 82% of the U.S. tablet market

Also-rans from Samsung, Motorola and others don't seem to have made much of a dent

"Despite the addition to the market of new tablet computers like the Samsung Galaxy and the Motorola Xoom, in the United States, Apple’s iPad is still dominating the conversation – and market."

So begins Nielsen's summary of the results of a survey of U.S. tablet owners fielded in April.

Apple's (aapl) iPad had the largest share (82%), split between Wi-Fi only models (43%) and 3G + Wi-Fi (39%). That's down from the greater than 90% claim Steve Jobs made at the iPad 2 launch event in early March.

Samsung, Dell (dell), Motorola Mobility (mmi) -- with 4%, 3% and 2%, respectively -- were overshadowed by Other (9%).

No big surprise there. Tablets based on Google's (goog) Android operating system haven't exactly taken the world by storm. More interesting, to us, was what Nielsen learned about how tablets have cut into the use of PCs and other electronic devices. Specifically:

  • 35% of tablet owners who also own a desktop computer reported using their desktop less often or not at all
  • 32% of those who also owned laptops said they used their laptop less often or never
  • 27% of those who also own eReaders said they use their eReader less often or not at all
  • 27% who also own portable media players use their media players less often or not at all
  • 25% tablet owners who own portable games consoles are using those devices less often, if at all, since purchasing a tablet.
