I finally bought a consumer Rift after a couple of years with the DK2, mainly because I wanted to try some of the games that use the touch controllers.
I have to say, it's well worth it! The CV1 fixes almost everything that was bad about the DK2 (single cable, integrated headphones that are actually good, built in mic, better resolution) - although it does introduce a new issue of the 'god rays'.
The only trouble is, some of the touch games are so good I've been playing less and less ED. Space Pirate Trainer is brill!
