Is OLED worth the price?

[Peh]

Depends on what you use it for. It is not suitable for attaching a PC on it due to burn ins. Same as gaming.
They still have the same flaws as in the beginning:

Lower brightness compared to LCD and decreasing further with time.
Low lifecycle
Burn in
Higher latency in regard to non oled.

But it's perfect for watching movies in a dark room.
