The new 15-inch T15 is the largest VAIO Ultrabook to date, and it doesn't depart from the silver, brushed-metal aesthetic we've seen on Sony's ultraportables dating back to the T13.
The silver, brushed-aluminum chassis is sleek but not slippery to the touch, and the reflective HP logo on the back doesn't strike us as too obtrusive (you won't see it most of the time, anyway).
