Josh Marshall, publisher of Talking Points Memo, looks at traffic on his site and points to the still modest but continually increasing share that 'mobile' is taking:
The additional wrinkle here is that 77% of that mobile traffic you see in the chart is from iOS devices, i.e., iPhones, iPads, iPods, etc. So give or take, around 40% of the visits to TPM come from computers or devices that use an operating system built by Apple. Compare that to 20% only 5 years ago.
The question is, is this really mobile? iPads for example are far more likely to be connected via wireless rather than through a phone company and screen-wise, it's a whole different user-experience. For purposes of analysis, I think it'd be far more helpful -- in fact, increasingly so -- to approach the data as 'mobile' AND 'tablet'.
