Here’s the latest from Pew Internet on usage:
56% of U.S. adults now own a smart phone. That is RAPIDLY increasing. 91% of adults have cell phones.
Virtually identical percentages own desktop and laptop computers. Not much over 50%, so it is clear a LOT of people use only a laptop as their main computer. Based on trends that is about to cross, in a few years probably twice as many people will own laptops (meaning a lot fewer will own desktop computers).
In short – to quote The Who – America is “Going Mobile.”
If Internet marketing is at all important to you, this is a trend you need to pay attention to.
