A few years ago, I was messaging a friend and offered to email him a file, making the assumption he would simply pull it up on his computer when he got home. His response was more jarring to me than it should have been.
“I don’t have a computer.”
The idea that my friend might only get online through his phone did not even occur to me. It should have, because I had already been developing mobile-friendly websites for a little while, but it didn’t. With the evolution of mobile devices and cloud services, more and more people don’t really need a computer on a daily basis.
