Kids don't do much research, they go for what people (friends) know of. The iPad has a "name", just like Kindle Fire. Android tablet is not specific enough to be singled out so they are usually just called "tablet".
My son wants an iPad, but really he just wants a tablet, any tablet. He's not getting one (I want a Surface or some tablet first!), I've joked about if *I* get a new computer or tablet, I may be willing to give all of the kids (collectively) my aging laptop. Seems fair
