Normal people buy computers at a retail store and use it in the factory configuration indefinitely. They think about changing their OS in the same way you think about changing the type of hem stitching on your slacks.
This is just absolutely beautiful. My grandmother would often identify stitching on my slacks. I was, quite literally, blind to it!
I don't care about the hem on my pants. My pants either work, or I get a new pair. This is most people's relationship with their computer.
I'm telling myself that this is an intentional "blind hem" joke.
