VAIO, the laptop brand which used to be owned by Sony, announced yesterday two new Ultrabooks. The Vaio Z is an acrobatic slim Ultrabook that can be used in multiple viewing modes, while the screen of the VAIO Z Canvas can be completely separated from the keyboard, resulting in a fully-featured Windows tablet.
