Sony, although shaky in its quality sometimes, is possibly the only company that offers cutting-edge ultra portable notebooks to its users. It’s usually the only company to have the latest technologies packed in some of the world’s thinnest designs ready to go. This time again Sony’s VAIO series expects to add a latest ultra portable notebook, the VAIO TZ, to its product line with Intel’s Core 2 Duo microprocessor, Windows Vista and a plethora of other options that should satisfy the road warrior in you.
