The reverse is also true. If the market can always sell you something with the idea its better than what you have it encourages you to buy the next thing.
A fluff example was when "digital" was a bling word. Speaker manufacturers started putting "Digital Ready" . Which meant absolutely nothing. Lol
And I hardly think an extra $50 to $100 eould put folks off the Go if it used the same Ips Igloo 120hz hdr screen. If anything folks would grab it for sure.
Just the fact the research suggests less is sufficiemt for a decent experience not to be confused with best. Add this & the fact they wouldn't want the Go affecting Rift sales if they made the Go better.
