Since just about all of the TV/monitors being produced today are not interlaced, is there yet a practical choice to replace my 13" industrial/broadcast grade monitor?
I'm using the apple 23" cinema display for editing, connected to a JVC CRT for viewing and color correction.

As stated, since the average viewer is purchasing either DLP, LCD or plasma displays, what is everyone switching to for editing confidence?

I would still stick with an interlaced monitor for SD work, since many people will still be seeing material on CRTs. You'll be able to spot artifacts like interlace flicker.

With progressive displays, many of them have poor de-interlacers. And a lot of broadcast will still be interlaced, so that material will get run through the de-interlacer. There isn't much point in monitoring for de-interlacing artifacts, since there isn't much you can do about them. As well, de-interlacing performance and artifacts depend on the de-interlacer in question.

Agreed.
can't help but look for more desktop space and a lighter box though.
