We know that smartphones and tablets are popular, but just how many US adults own a smart device? According to a new study by Pew (Pew?) Research - half of all adults in the US own a smartphone or tablet.

Pew Research says that their findings have "major implications for how news will be consumed and paid for" in the future, with close to 20% of mobile news respondents revealing that they had paid for an online subscription within the last twelve months.

Roughly half of the tablet-based readers said that they now spend more time consuming news, while close to a third of readers said they are receiving news from sources they didn't before. Some of the numbers from Pew Research's results are also interesting, where last year 81% of those interviewed owned an iPad, where this number has dropped significantly to just over 50%.

48% of the people surveyed owned an Android-based tablet, with the survey coming from over 9,000 adults from late-June to early-August.
