But I've read more than a few people in the VR space (game journalists, developers) say that there is something special about the Gear because there is no cable. There's nothing you have to keep conscious of so you don't trip over it or feel it on your back breaking immersion.
The Gear VR could be enhanced with better tracking, and as new phones come out it will get better processing power. I think Fowler is right.
VR is very new. Let's say your a consumer who wants to play with it. What's a better investment? $2200 in a PC and a Rift, or $100 that clips on your phone (assuming you're on Samsung)?
If you just want to try it for now, play around a bit? The Gear is very compelling.
(I'd love one, but I use an iPhone. I've got a PS VR on order though.)
