even if this is true that the life time of this OLEDs is about 5000h, if the price is low enough that would make them a very good choice. if you use it every day for 5 hours that still gives you about 3 years of use. a lot of people didn't have their 15inch monitors in use for 3 years before they bought a 17inch screen. so it would be a good buy.
but these OLED displays are not with us yet and I don't see them coming into the shops in the next two years. so I hope for the price of TFT LCDs to come down because I think they are better for long time computer work than CRTs.
respect!
