The last time certain family members asked me for a computer recommendation, I gave them a detailed breakdown of which MacBook they could get to meet their lightweight needs for the next decade. They thanked me, agreed, went to Best Buy, and came back with the laptop that the salesperson convinced them was better "because he knows computers". It was an utter piece of crap and they've had nothing but problems with it.[0]

Had this existed when they were shopping, I would've just asked what color they wanted it in, ordered it for them, and been done with it.

[0] OTOH, that got me out of all future tech support duties. "Hey, why can't I connect our new printer to it?" "I'm not sure. Does that Best Buy expert still work there? He might have some suggestions." (Phrased more politely IRL because I'm not a monster, but the intent was there.)
