Tom's Hardware checked out the HP Spectre x360 15-inch (OLED)
A quote from the article:
HP’s flagship 2-in-1, the 15-inch Spectre x360 ($1,329.99 to start; $1,879.99 as configured), just got a bold, bright new addition: an OLED display. That panel offers brighter, more vivid colors and deeper, darker blacks for a better image. That’s on top of an eye-turning design that the company launched this year with edges cut like diamonds and powerful speakers. But on this model with the OLED screen (which costs $150 more than the same configuration without the vivid screen), the battery life is lower than average. And such a beautiful display doesn’t deserve to be surrounded by such horrible bezels.HP Spectre x360 15-inch (OLED) Review
