Technology advances fast, and it's advancing so quickly that it could give this equation a run for its money.
While yesteryear's device may be considered today's relic, there are some ancient technologies that can cost a fortune to own.
Especially if those devices were developed by one of the most famous companies in the world, and are limited in numbers.
Meet, the Apple-1, the very first product that came out of Apple, the very product that propelled the company to become a tech company soon-to-be feared and loved by many.
With only dozens of functional Apple-1 computers available in the world out of the original 200 that were manufactured, one that came up for sale will certainly fetch a lot of money.
And this time, one Apple-1 computer auctioned off on eBay has been sold for $340,100.
The Apple-1 computer in question is known as the "Schlumberger 2" Apple-1, and it has been restored to full working condition.
The device is said to feature "almost all period-correct components" with the appropriate "make, part, and production date for an Apple-1 'NTI' board," with the exception of some multiplexor ICs.
The Schlumberger 2 Apple-1 is a second-batch Apple-1 computer that was originally purchased by an executive at oil services company Schlumberger Overseas in 1977.
What this means, the Apple-1 is believed to be one of the last Apple-1 computers assembled in the Jobs in his garage in late 1976 or early 1977.
Making it more unique, the Apple-1 computer has its motherboard signed by Steve Wozniak, the Apple co-founder who designed it, and assembled it by hand.
The Apple-1 was the first Apple product created by Steve Jobs and Steve Wozniak when Apple Computer was founded, and there are few left in existence.
Made when Apple was just incorporated, Apple-1 computers were hand-built, and tested personally by Steve Jobs and Wozniak, with help from Patty Jobs and Daniel Kottke.
Apple-1 computers were the first computers that marked the start of the personal computer industry, and were also the first personal computers that came with a warranty.
"It was guaranteed to work," said Corey Cohen, an Apple and technology historian.
"Prior to that, there were other computers. They were kits. They mostly didn't work when you got them."
Apple-1 was the computer that Apple founders wish "isn't something to be afraid of, a computer is something that can be part of your life and can help improve your life."
Before this, an Apple-1 in a Koa wood case sold for $500,000.
