Chorded keyboards are silly - just like chorded instruments. Can't argue with the obvious superiority of the 2000-keyed guitar rather than just one with 6 strings and 20 frets.
Also, it's not like you'll be using keyboards for half a decade, so yeah... learning something like that would be a total waste of time.
