Tech site Silicon Alley Insider has published the results of its survey of iPad owners, to find out how they are using Apple's tablet.
It finds that two thirds of iPad owners use the device for between one and five hours a day, and that nearly 30% say it has become their primary computer.
39.4% of iPad owners have downloaded 20-50 apps, while 16.7% have downloaded more than 50. However, web browsing remains the most popular activity for the device, followed by email and social networking.
The survey found that 28.5% of iPad owners have paid for 1-5 apps, 24.5% have paid for 6-10, and 27.8% have paid for 10-20. Most people are using less than 10 apps on a regular basis, however.
Finally, the research found that 74.5% of iPad owners are reading e-books on the device, but that Amazon's Kindle app is more popular than Apple's own iBooks.
