I bought a Ducky keyboard: http://www.duckychannel.com.tw/page-en/One-TKL-RGB-version/

It has an on-board ARM chip and firmware that handles 100% of function through simple Fn key combos: http://www.duckychannel.net/download/user_manual/DuckyOneRGB...

Off-topic but related: Nvidia's Geforce Experience software recently implemented a similar system - you must now create an account and log in to use core functions that previously didn't require any network connection.

That facilitates their keylogging ;)
