A survey by copywriting firm Cooper Murphy Webb found that iPad owners use them largely for entertainment purposes.
Almost a quarter of respondents said it had become their primary entertainment device, ahead of TV and trailing PCs by just nine percentage points.
To a large extent, iPads and possibly other tablets compete with e-book readers, gaming consoles, mobile phones and TVs more than other PC form factors.
The iPad was considered the top delivery method for newspapers and magazines, and its popularity for books was even greater. Some 41 percent of iPad owners preferred to read on the device, compared to 36 percent of respondents who liked hard copies better.
Also, iPads were the top gaming device for owners of the tablets, beating out consoles by two percentage points.
A study by Ball State University researchers suggests new iPad users deem it best for leisure activities, not content creation.
