I love this... I haven't had the courage to "spend" my sticker collection on my current laptop, as they obviously don't last forever.
A solution could be to photograph the old cover, and print it as a full-size sticker as a starting point for the next laptop!
Keep it going!
I did that to my Facebook pfp (they also have stickers) - after a few years it became this abstract, glitchy work of art. I don’t use fb anymore but still remember that fondly
