I bought an Asus VW222U and have been using it for two days now.  I'm comparing it to my 5 year old ViewSonic VX900.  Initial thoughts:
BRIGHT!  WAAAAAY TOO BRIGHT!  My golly, turned brightness down to 0.  If anyone uses it as is out of the box, you'll burn holes in your retinas.  Once I turned down the brightness, I worked on the contrast.  
And I simply can't get comfortable with the contrast for office type work.  If I turn up the contrast, the letters on the screen are ?pinched? and too narrow.  Seems like the white is bleeding into the black of the letters.  To combat that, I have the contrast (and brightness) both at zero.  This makes the background of my document almost gray, but at least the text is bearable and I can read it fairly nicely.  However, still not nearly as nice as my ViewSonic for text.  On my ViewSonic, the brightness is on zero, and the contrast at about 50%.  The white is pretty white, yet text is black and very readable.  
Overall, I'm quite disappointed.  I can't imagine how this would get a good review for office type work.  Even light work, I can't get comfortable looking at it.  
Now, the pros:  the colors blow away the ViewSonic.  Pictures that looked okay on the ViewSonic are MUCH more vibrant on the Asus.  Again, I played with settings, and found that if I turned up the saturation to 50 it looked best.  (Needed to switch to ?scenery? mode in order to access the saturation menu choice).  
Also ? zero dead pixels.  And nice styling.  
I don't think I'll return it, not worth the hassle since I got it for $200 after MIR.  And I can always use the ViewSonic for reading and office work, and use the new monitor more for pictures and video editing.  But I simply can't recommend it.  Not sure if this is a different screen from what was initially sold as VW222U, but it is just BAD for text on a white background.
