Here is an excerpt from a report entitled "Zero to Eight: Children's Media Use in America" The report is complied by Common Sense Media.
COMPUTERS. Computer use is pervasive among very young children, with half (53%) of all 2- to 4-year- olds having ever used a computer, and nine out of ten (90%) 5- to 8-year-olds having done so. For many of these children, computer use is a regular occurrence: 22% of 5- to 8-year-olds use a computer at least once a day, and another 46% use it at least once a week. Even among 2- to 4-year-olds, 12% use a computer every day, with another 24% doing so at least once a week. Among all children who have used a computer, the average age at first use was just 3 ½ years old.
MOBILE MEDIA. Half (52%) of all children now have access to one of the newer mobile devices at home: either a smartphone (41%), a video iPod (21%), or an iPad or other tablet device (8%).
More than a quarter (29%) of all parents have down- loaded "apps" (applications used on mobile devices) for their children to use. And more than a third (38%) of children have ever used one of these newer mobile devices, including 10% of 0- to 1-year-olds, 39% of 2- to 4-year-olds, and 52% of 5- to 8-year-olds. In a typical day, 11% of all 0- to 8-year olds use a cell phone, iPod, iPad, or similar device for media consumption, and those who do spend an average of 43 minutes doing so.

It makes for some interesting reading and further supports the fact that we need to be doing a heck of a lot more with technology in our schools.
