So how does this relate to screen size? As smartphones become our primary devices, doing the jobs once held by computers and even televisions, we need a product that can change, like a chameleon, to serve all of these functions.
Before 2010, the extra real estate was unnecessary. After all, we were using phones mostly for making calls, listening to music, or doing a bit of light web-browsing on bad mobile interfaces, making mental notes to do our real work when we got back to our computers.
Today, the web--from site interfaces to television to native apps--is often designed primarily for the mobile format. The smartphone is no longer just a phone, but a hybrid of devices--and increasingly, the most common way to interact with the world. A bigger screen allows a mobile device to play all of these roles at once.
We've ridiculed the so-called phablet (a phone that's nearly the size of a small tablet), but perhaps we've been headed in that direction all along. Maybe bigger is better.
