Today, iSuppli noted that the tablet is largely behind current trends, and is projected to become the fastest-growing segment within the space. That's largely linked to the success of the iPad.

More than 300 million tablets are expected to ship by 2015, which is 15 times greater than shipments in 2010, according to iSuppli.

"No other Internet-enabled device in the next four years will come close to that kind of growth," the firm reported.
