With the announcement of the Razer blade stealth and the Razer core. As well as Asus's external GPU dock, there comes the question about bottlenecks and if the ultra-book/external GPU is worth the money. As a student with very little space, I also need a laptop for class, these seem like great options. Although I want to know what you think about the whole idea and current products on the market, or new products to the market.
