This is good laptop and good quality and fast prosserer and highest brand and original company and ultraportable laptop. It’s made of durable materials, has long battery life and its performance often surpasses that of rivals like the Lenovo ThinkPad X1 Carbon and the 13-inch MacBook Pro. Plus, this system is half a pound lighter than the MacBook Air. But the Vaio Z’s flat, mushy keyboard makes me question the entire value proposition.
