For your information I run dual Viewsonic 17" VP171b monitors. I know all of which you speak of, I do my own research and buy what I think is the best deal. But I also know that Apple's displays are among the best out there.
To answer your question YES, I have looked at the other competition out there. Here is your 173p monitor specs:

This monitor DOES NOT compare to any of the Apple display's except the old models. Wow 700:1 contrast ratio, nice one.. except it will be utilized by almost no one. Now look at the pixle pitch, much lower than apple's displays, this means not as clear of a picture, in other words less pixles per inch.
Second, let me look at the response time, 25ms compared to Apple's 16. Now you lose out on the fire wire hub, and the nice enclosure.
It's clear you really aren't providing me with any of the information which you talk so highly about. You make claims without links or background to support them. I have proved my point from various sides now, doing the research to find the exact specs which you did not. The Apple monitors are clearly better, if you find your cheaper displays, with worse pixle pitch, and slower response time to look and work better than an Apple display that is fine by me... just know that your claims are out of place.
that being said I have yet to see the "new" apple displays, but just from people that have, they sound amazing. Hard for me to think that Apple wouldn't put out one of the best displays on the market, esspecially after such a long wait...
