I've recently spotted new Dell/HP with 4k displays and small bezels and those look great and have 32Gb of RAM.
My top-of-the-line MacBook Pro '17 screen is noticeably worse and it has only 16Gb of RAM. I know that there's no LPDDR4 support yet -but- that's developer machine.
With Docker, Terminal, cmake and all those things it barely lives for 2 hours on battery anyways, so I might as well just have a more powerful portable machine.
But the best thing is definitely the 4K screen on those HP/Dells: With the default scaled resolution that Apple introduced last year things look pixelated, while on 4K they don't. For a person who spends 12+ hours a day in front of laptop screen that's huge.
Maybe colors are not that saturated but I don't care if my VSCode theme displays 1 billion colors more. Neither iMac Pro nor MacBooks are developer machines anymore. Creative professionals -- yes, but not developers.
