Instead you could adjust your habit of where to find the ESC key for the sake of ergonomics (Caps Lock is much bigger and closer), like I did years ago, and take the colorful lights as a bonus.
What about the fact that I frequently jump between machines, many of which aren't mine? It's the same as people telling me to learn the Dvorak layout. Any possible productivity gains are lost in forever remembering what keyboard I'm on.
