Well I finally got a quest today...
I'm surprised that while it does look a little better, the resolution doesn't seem like a huge jump over the original rift... I think I was expecting a little more from the specs. I definitely get the discomfort point too, it's fine for a short time but with longer play periods it definitely ain't nice to wear for me... Have ordered a AMVR facial interface which should get here tomorrow, will see if that improves things.
I was pleasantly surprised by the audio, although it clearly lacks bass it is much better than expected. I will still probably look into doing the DAS mod for comfort and better audio though.
