Still not sure..
Used a DK1 and DK2, owned the consumer version for all of two weeks and have even had a loan of a Vive.
Just not sure any of these is quite ready for me yet, motion sickness was less of an issue on the newer versions but still present, my main issue was cables and long term comfort. The cables break immersion if it's a game where you have to look around a lot (better on ones like Elite Dangerous) but the biggest draw back was comfort, I found them uncomfortable if used for more than an hour, warm face, dry eyes.
I'll look again in 5 years thing is as a spectacle wearer I loved using them, It could be bloody amazing given a little more time to mature, downsize and reduce reliance on cables.
