Well, Apple have started the trend, and I suspect many others will follow. Just as CRT TVs are disappearing, Apple have dropped the CRT from their eMac and introduced an LCD version.

I still like CRTs, and there are still colour issues with many LCDs that need to be addressed (most cannot match even a cheap CRT for colour range), but LCDs have many other advantages, like lower power costs, lower desk space costs, and are generally easier on the eyes.
