Yeah it would be nice not needing a dedicated got anymore on a laptop but the integrated gpus perform considerably worse, so until then having the option to have a dedicated gpu is a nice thing to havein my opinionSome customers (many customers?) would like to optimize affordability, reliability, and battery life in a high end laptop. I'm one such customer. There are others in this thread.
On the other hand, there are some customers who are opposed to circuit integration and want to give up affordability, reliability, and battery life in order to have retro discrete technology. It's not clear why they don't want to go all the way back to discrete transistors -- or perhaps some of them do.
Integration is the vector of progress in the realm of electronic circuits.
