It gets you about 90% of the image quality and 0% of the motion quality. Simulating CRT motion quality on a sample-and-hold display requires around 1000Hz refresh rate.
Well, seems like we're getting there in terms of refresh rate, if not there already, so still easier and cheaper than making new CRTs.
