Kinda accidentally won a vive on eBay and after playing with it for a few days I have to say the experience is great fun :p
My biggest complaint with it is that it can feel like wearing scuba mask, if they could make it feel more like our normal vision then it would be pretty much perfect.
It really depends on the game though, some look or feel horrible (pixel density really shows or turning is jittery) while others offer an experience that just can't be matched by normal games (super hot is amazing to play) and games with great graphics truly look amazing (alien isolation is stunning).
It's just far more important to play a well made game compared to a poorly designed game (and it can be quite hard to tell which is which right now as the market is still very new so reviews and prices are all over the place).
Its certainly going to be an expensive adventure as the games are generally short and expensive (compared with other steam stuff but not compared to brand new AAA titles).
Room scale was the biggest worry for me as I have a pretty compact room with sloping roofs (as I have an attic room) but with a mod to move my virtual play space around (open vr advanced) I found it's not really an issue as long as I don't get carried away and forget to watch for walls etc I can play perfectly fine.
Wires were the other issue but with some simple DIY I don't event notice them, I even built myself a neat cable pulley system using those stretchy key chain things to hold the headset wires above my head while I play but still have the freedom to pull on and stretch the wires.
