In January of this year the Pew Internet Project released survey data that showed 19% of US adults owning tablets (iPads). That was up from just 10% only a month before in December. Now comScore has released data showing that roughly 24% of smartphone owners also have tablets.
If we extrapolate these numbers, the Pew data suggest that there are roughly 42 million tablet owners in the US (as of January 2012). The comScore data argue the number is now 55 million. These figures seem entirely reasonable. Apple CEO Tim Cook reported 55 million iPads sold to date in February.
People use the term "tablet" but the market remains largely about the iPad. The only other two models with any traction are the Kindle Fire and the Samsung Galaxy Tab. According to Gartner Apple's share of the tablet market will be 61.4% at the end of the year. IDC says Apple had a 68% share of the global tablet market in Q1 2012.
Both of these figures are incorrect and largely based on shipment estimates. Shipments don't equal sales to consumers.
Perhaps I should say instead that people may be buying other devices but it still doesn't matter. According to ad network Chitika, based on an analysis of millions of impressions in the US, the iPad "accounted for 94.64% of all tablet based traffic." By contrast Chitika said that the nearest competitor, the Samsung Galaxy tablet, "boasts a lack luster market share of 1.22%."
Late last week ad network InMobi released its own tablet data, showing gains by the Kindle Fire and total Android tablet ad-impression share of 28%. That argues the iPad controls a 72% share of the total tablet market.
We're likely to hear an update of tablet numbers this morning from Tim Cook during the Apple WWDC keynote.
Back to the comScore tablet data: the company says that just over half of tablet owners are watching video on the device, while nearly 10% are doing so every day.
A year ago in March AdMob found, based on a survey, that 77% of tablet owners were using their PCs less. In addition 28% of respondents said that the tablet had become their "primary computer." Clearly tablet ownership does cannibalize PC usage, while smartphone ownership may complement it. Roughly 80% to 90% of tablets are used mainly at home.
Once Microsoft puts Office on the iPad it will become a true PC substitute.
