Your smartphone, your tablet, your personal computer, they all use something called dynamic random access memory. You probably know it better as RAM. According to the research firm IHS iSuppli, something amazing happened in Q2 2012. For the first time in recorded history, personal computers consumed less than 50% of the RAM chips available on the market.

To give you some perspective, the PC has been around for roughly three decades. Android has been out for less than five years. Last week we heard two very important numbers: More than 500 million Android devices have been activated and more than 400 million iOS devices have been sold. Those devices, along with your Windows Phones, BlackBerry smartphones, and other mobile platforms, are to blame for the “death” of the PC.

“The arrival of the post-PC era doesn’t mean that people will stop using personal computers, or even necessarily that the PC market will stop expanding. What the post-PC era does mean is that personal computers are not at the center of the technology universe anymore—and are seeing their hegemony over the electronics supply chain erode. PCs are no longer generating the kind of growth and overwhelming market size that can single-handedly drive demand, pricing and technology trends in some of the major technology businesses.” – Clifford Leimbach, Memory Analyst at IHS

Clifford says it best. Computers simply aren’t at the center of our lives anymore. Now yes, we need PCs here at Android Authority to give you guys the news you crave, but most people do a lot of their computing on the gadgets that live inside their pockets. IHS iSuppli estimates that by the end of 2013, more than one out of every four memory chips will end up inside a smartphone or a tablet.

Take a second to let that sink in. That’s less than 18 months away.
