In addition to the upgraded Blade 15 Advanced, Razer is also showing two interesting prototypes at CES. The first one sports a 240 Hz full HD display, while the other one comes with a 4K OLED touchscreen. Sadly, these might not make it to the masses anytime soon, since both are only being evaluated at this stage.

I don't care about touchscreen, and always thought 4K resolution is not needed on laptops, but I do care and have been waiting for years for an OLED screen on a notebook, so really glad they're finally coming this year!
