I would highly discourage including a keyboard or mouse. If you are already spending $2700 on a VR computer I suspect you already have a keyboard or mouse you prefer or want to invest in a setup of your choice. No point in creating eWaste to drive home the point that this is a computer. And to that point you say that they need to emphasize that it is a computer and not just another headset (to the point of saying included a keyboard and mouse), but then bring up their use of terminal windows in their marketing (I agree though they should show other things as you suggested)?

Two of your points in your comment seem to be lambasting the fact SimulaVR aren't advertising towards the lowest common denominator of people buying tech. It is a $2700 computer and display. Who exactly, that would ever actually purchase this device, would not understand it is a computer (or that it can come with one if you aren't doing stand alone), or not realize that if it can be used in a coffee shop it can be used in a home office?
