If she has one or two siblings, in a school district that equips students with laptops, in a household with parents (or grandparents, ugh*) who are giving their kids laptops, if one or two of those laptops have been replaced/upgraded before the old one became defunct, a house could easily end up with 7 working laptops in it. And it's not surprising that a teenager who's painstakingly choreographing and posting viral videos to the internet has ready access to all 7 of them.
