To be fair Oculus are one of the ones in the industry looking beyond games. Look at Oculus Medium[1], it makes something that was extremely fiddly and required hours of practice into something instantly intuitive.

I don't actually think VR will hit the mainstream, work like spreadsheets just don't benefit much from being in 3D space. The true magic of VR is the hand tracking, being able to interact with computing with both hands in 3D space.

Definitely feel VR will find it's workplace niche in the creative space rather than standard office work. Worth mentioning too that games are an innovation driver, so don't discount them so fast.
