For the average geek like us, there's nothing more satisfying than watching a gadget skillfully torn apart by its creator. That's why we're slightly envious of Engadget Chinese, who saw Sony VAIO Z Series project leader, Takamitsu Kasai, explaining the differences between the old and new VAIO Z literally part by part. Hightlights include Sony's proprietary Quad SSD (so not user-upgradable, sadly), a redesigned heatsink to accommodate the new chips' higher TDP (thermal design power), and various features of the "one-piece milled aluminum" and "hybrid carbon" chassis. Of course, all we really care about are photos of the naked VAIO Z, so go ahead and gorge yourselves after the jump.
