Google is still pushing these dumb machines (they have no operating system, no local storage and rely on an Internet connection to operate, so they are dumb machines) to schools. Students with these will have to learn to type on machines without a spacebar. Programming, home work, essay writing, even searching on Google will be more difficult. Do we really want our students to learn on machines that won't carry over to the real world?
We need the spacebar, let's fight to keep it.
