Good point - but don't forget that a 1080p monitor will still resolve a 1080i signal more smoothly, with less flicker and without bothersome combing errors. It is just like with a 480p television deinterlacing 480i DVD materials. The 480p set does make the 480i image appear smoother, with less motion artifacts. Despite the apparent lack of 1080p signals or inputs currently scheduled for release, it could make 1080i broadcast HD and 1080i encoded HD-DVDs look even better... I guess it remains to be seen whether the difference will, well, make a difference.
