Per, I hadn't looked at recent data so those numbers look really impressive. Last time I looked we were quoted 15000 hours to 50%, which was no good for a product with an expected lifetime of 10-20 years. We were concerned by burn in as the display would be static for 99% of the time, so we even considered slowly moving the display around to get a "wear levelling" effect. If 400,000 hours to 50% is real, then there's no reason not to use them.
