Which is why we have RGB Monitors in the first place.  Call me behind in 
technology when I am using an Apple IIgs as opposed to a Power Mac or PC, 
but dont insult my electronic intelligence by saying adding chroma 
demodulation where none is used now is better than RGB video!

Anyone with half a electronic brain knows that adding anything in the 
signal path of an electronic signal will degrade that signal.

This is not a putdown of the Electronic Turtle per se, just its 
advertising which is very misleading in my book.  The product may perform 
admirably and may even look better than what we presently are using do to 
the age factor and the use/abuse we subject it to.

All monitors/TV's have a crud area in the 3.2 to 4.2 MHz range when using 
standard NTSC chroma demodulation (diff freq area for PAL and SECAM) 
where chroma information interferes with luminance information.  Comb 
filters and other hi-tech sounding items help the interference problem 
but in the final analysis, the interference is still there.

RGB video does NOT have this problem because there is no demodulation 
taking place so no intereference because from the start you have 
separated red video, green videoand blue video and the signal doesnt get 
any clearer than that.

Also NTSC RGB video monitors are still availiable brand new with hi-tech 
picture tube dot-pitch, etc all the way to 33" size.  And for the record, 
16/9 aspect ratio monitors are availiable today also as they are making 
their way into the commercial video game market.

By the way, I DO NOT sell monitors for a living, however I do fix them 
for a living.
