Ultimate performance and design: ultra-mobile new VAIO Z Series from Sony

The performance of VAIO Z Series is taken to new extremes by the unique
Power Media Dock, a monolithic expansion module that links with VAIO via an
optical cable. The proprietary port can also be used to attach regular USB
devices to VAIO when it's not docked.
Featuring high-speed I/O data transfer based on the architecture codenamed
'Light Peak', Power Media Dock boosts graphics performance while adding
numerous extra connectivity options. It includes an optical drive for even
greater business productivity and satisfying HD entertainment.
