Why I'm not buying the most powerful MacBook Pro anymore

In 2012, I bought the most powerful model of the 15-inch MacBook Pro because I knew its Core i7 processor would keep up for several more years than a MacBook Pro with a less powerful Core i5 processor.

The concept is called "future-proofing." Basically, I buy a device that's way more powerful than necessary for my current needs in anticipation for the future when operating systems and apps will require more horsepower.

My plan worked. My five year old laptop still runs incredibly well, even by today's standards, and I have no need to spend a couple thousand dollars on a new laptop. In fact, I could probably squeeze out another couple years out my trusty old 2012 MacBook Pro.

But future proofing has one big drawback.

You see, I don't really want my five year old MacBook Pro anymore; not when I see all the cool new and improved features on newer models.
