I had equipped the family with identical corporate-refurb laptops - when you have any of 4 laptops in a family room, it was a way of not getting my laptop taken by my kids to school one day...

Back in the office days, it was also a way to identify a corporate laptop among a sea of identical models.

Also, like I don't wear branded clothing, I like to cover the device brand.

Back when I worked at Apple no one had stickers on their laptops (gasp, who would dare!). But everyone had identical MacBook Pros, and when we had meetings, they would go in the center of the table and then everyone would have trouble telling them apart. So I got a couple of gold star stickers like you give to children for my laptop.
