Just curious what the issues are with Logitec K400 as i have a K400r and it works well as long as i'm not more than 3m from the receiver.

as per the wiki, it's known to be problematic on the dev mode boot screen, which makes it useless for dual boot users. Once the OS is loaded, it works fine.

Thanks Mat, via the chromebox wiki in your signature, i also found mention of K400 issues in the trouble shooting section.
In that wiki, there was also a link to this thread that discusses keyboards that work in chromebox developer screen.
