A 23" monitor is going to happen and it will be a good thing. Watching a DVD on the 20" monitor is ok, but kind of small. Apple is moving the iMac to be a multimedia station for movies, music videos, and pictures. And all of those things would work better with a bigger screen. I think the price point will be around $2000 when they do it, which isn't that high. The 20" iMac sat that the price range for awhile. I don't think it's that far off considering the 20" is around $1700. I think the 23" will come right after the intel processor change, which could be 1+ years.
