This. I work as a sysadmin and the number of keyboards I have to interact with makes using anything other than QWERTY more of hassle than benefit. On a typical day I will interact with my phone keyboard (blackberry priv, hardware keyboard), my primary work desktop, my secondary desktop (used by colleagues sporadically), my gaming PC (used just for gaming), and my personal laptop. Now add the times I have to jump onto someone else's station or a family member's system and the constant context switching is just not worth it. I tried dvorak some years ago, but found it more trouble than it was worth it, since everyone else doesn't use it.
