Oculus Rift Dk2 To Buy or Not to Buy??

Recently I have been contemplating buying the Oculus Rift Development (Oculus Rift Dk2).  It retails for ~€300 and is a Virtual Reality Headset.  It would be a really cool experiment to develop a Virtual World and see where the boundaries, if any are.  Their developer tools seem really good and worthwhile taking a glance at them even if only for fun.  But €300 for an experiment seems indulgent with no solid business case behind it.  Has anyone used the Rift for a non gaming related field?  Id love to hear from you.

As always if you have any thoughts or want to discuss further then lets have a real conversation and get in touch on twitter @naoimigillis.
