I really hope this recent trend of offering 100% wide-gamut color display option in OLED only is just a fad. From reduced battery life to PWN, I can think of several reasons why someone would opt for IPS over OLED.
Lenovo's new ThinkPad P1 G6 performs admirably as a mobile workstation with fast GPUs and a vivid IPS display. At the same time, it replaces the previous multimedia flagship ThinkPad X1 Extreme, which is a questionable marketing choice.
