I'm typing this on a PC where I did the same thing as the author. Over the past 10 years, I've swapped out a part every two years or so to keep it running the latest and greatest. But the CPU is five years old and still running fine. I'm planning to donate it to a non-profit to replace a computer that's almost 10 years old and also still running fine. There was a time when you felt like a new PC was obsolete the second you took it out of the box. But that was because we were just scratching the surface of what we could do with new hardware. We're now at a point where it's hard to find consumer and business applications for all the spare hardware that you can afford. Mobile adoption has been so quick because everyone is buying devices for the first time (tablets), or there is an incentivized two-year replacement cycle (phones). But I'm still using an original iPad that works just fine, and a 3 year old cell phone with no reason to upgrade. Eventually, I think we'll start to see the same leveling off in mobile as well.
