The issue with text on OLED panels is typically due to the sub pixel layout, they tend to use different sub pixel layouts to traditional monitors which causes issues with subpixel rendering and can make text look blurry or have color fringing.
However, recently you can now get OLED panels from LG with RGB stripe sub pixel layouts (matching traditional monitors) which eliminates this problem and text should be just as good as an non-OLED display.
That sounds like something someone would write a driver for that then installs a rootkit
Yeah, I'm using one (the Alienware 3926), and it's fine. You'd never know it wasn't IPS except that it's better off-axis and has vastly better blacks and no light bleed.
