A lot of people ask techie friends for advice on what computer to buy.
As argued by Paul Graham:
"So what, the business world may say. Who cares if hackers like Apple again? How big is the hacker market, after all?
Quite small, but important out of proportion to its size. When it comes to computers, what hackers are doing now, everyone will be doing in ten years. Almost all technology, from Unix to bitmapped displays to the Web, became popular first within CS departments and research labs, and gradually spread to the rest of the world."
