A 12% drop in luminance after 1000 hours for blue!? 7 and 8% for red and green!?
1000 hours is less than 3 hours a day for a year, which is easy to do.
The big benefits of OLED are 1) power consumption, 2) contrast ratio, and 3) color accuracy.
Sony's 11" screen eats 45 Watts, which is about the same as many 20" LCD's -- which have almost 4x the screen area. So, Sony's XEL-1 gets a big fat F at OLED benefit number one.
If the individual colors are fading at different rates...and at up to 12% per year...then color accuracy is going away pretty fast too; so, Sony gets about a C for benefit number 3, on my arbitrary scale.
And, as the luminance/brightness drops, the effective contrast ratio falls too. Even if the display's black emits no light, it'll still reflect light from other sources, so the contrast ratio is never infinite. Every drop in luminance is a drop in contrast ratio...but the ratio will probably remain higher than other technologies for at least a few years of use...so, I'll say A-.
I read somewhere that they use a repurposed Bravia board in this set. That is what probably eats all the power. It's not even HD so all the set really offers is a small form factor and high contrast. These are not things that I would personally want to pay a 10x premium on. OLED does look very promising but its still early days. Once the screen size gets bigger, the reliability goes up and the price goes down we may eventually be able to say goodbye to LCD and plasma.
OLED is too immature to promise anything. Those rates don't fair well at all. Considering the price to screen ratio, it's going to stay young for a while.
“That iconic Klipsch sound is here in full force, with crisp highs, delicate mids (which can easily have a bit more meat added with an EQ tweak) and tight, booming bass.”

A-, C, and F. That's not a good report card.
