4k monitor at 27 inches costs less than 400 dollars. Unless its 10 bit with 1ms response time for gaming. Who is spending $3500 on monitor setups besides gamers?
The fact you have to configure anything for scrolling to work smoothly on a web browser paints linux in a bad light itself.
The main reason i do not watch to switch to linux [apart from missing adobe catlogue and sketch] is stuff like the track pad, being able to navigate around using various gestures, having little things like invisible scroll bars etc. Subtle animations and visual queues really make the experience smooth. Its not even about eye candy, just seemlessness so your mind doesnt notice the workflow - which is what you want.
The latest ubuntu doesnt even let you drag drop on the desktop? i really want linux but it still seems miles away from sleekness of osx
