Business Insider recently surveyed 500 iPad users about their habits with some interesting results. Among the most interesting is that nearly 80 percent of respondents (77.6) said they use their iPads more often now than they did when they first got them, suggesting that, after the novelty had worn off, customers continued to use their iPads. Even more so, in fact.
The study also found that 71 percent of participants use their iPads between one and five hours per day. Additionally, 28.9 percent said that their iPad has become their primary computer. Personally, I use mine as a supplement, but my wife hasn't touched our MacBook Pro since the iPad came home.
Most participants reported spending the bulk of their iPad time browsing the Web (37.7 percent) while 39.4 percent claim to have downloaded between 20 and 50 apps (most people paid for about 10 apps).
There's more, of course, which you can read here. It's an interesting study with a decent-sized sample.
