I mean, I get it. I work in IT, so I probably know a thing or two about computers. And I really don't mind helping out.
My problem is that these people usually have absolutely zero understanding of technology or how any of it works. It's usually frustration with their 10-year-old laptop that hasn't had a proper update in just as long, and pretty much everything on it is completely screwed. Now they're finally ready to spend a decent amount of money on a new device that they expect to guarantee stability and speed.
The truth is, almost any reasonably modern device will give you exactly that, and it's actually pretty hard to go wrong. It's also true that every device will eventually become a pain in the ass if it's maintained the same way as the previous one. And while there are some differences that make one manufacturer better than another, It's sort of irrelevant for the your average casual office user.
You don't have to be a genius to recommend some ridiculously expensive, overpowered machine that guarantees great performance, but what's the point of having someone spend a fortune on an advanced laptop if all they're going to do is use Word and read the news?
What I usually do when colleagues or acquaintances ask me is keeping it as simple as it gets: Lenovo ThinkPad, Core i5, SSD. No overthinking, no reinventing the wheel.
Still be prepared to become the scapegoat the moment their new laptop decides to misbehave. And sooner or later, it will, because some people simply aren't meant to own a computer.
