Besides viewing angle, any other significant drawbacks from using PVA?
You get lower color saturation, and lots of color shift (you look just a tad off the 0 degree mark and many more picture details are revealed on the screen). Also, poorer uniformity is common with the PVAs. It is thought that the PVA is even 6-bit! Response time is worse too. I suggest that any company looking for the best way to screw people over take some hints from Dell.

Yes. Here is the measurement method, and here are the measurements for the LM201W01 panel.
If you want measurements of the end product (LCD, after putting in the DSP containing the overdrive functions), those will vary. The NEC 20WMGX2, which uses this panel, has been measured by X-Bit Labs as under <10 ms for all color transitions. The link for that is in the 20WMGX2's recommendation entry under the OP. I am going to take a stab in the dark and say the S-IPS 2007WFP comes in at 13-19 ms for all transitions. The PVA one is undoubtedly slower due to the panel type.
I feel really bad about Dell making us play the panel lottery game. I've recommended this LCD to a lot people since I got it, I hope everyone has gotten the S-IPS version.
Well, I have too until recently, and Dell is making us look bad. I don't buy their "supply and demand" theory. Nobody else has had trouble keeping the panels the same in all of their LCDs. Dell is the only manufacturer in history to swap panels like this. I just think that they are getting the cheapest they can find, but I also find it hard to believe that the price on the PVA and S-IPS panels varies weekly. It may vary by a couple dollars, but if the panels are that close in cost, why don't they just use the better one? Customer satisfaction down the toilet...
EDIT: After a little bit of research, I found that the newer revision 2007wfps wont tell you the panel model in the service menu, but Dell gives a different number to indicate the panel being used. "RT803" should be the code for LG/Phillips S-IPS and "PM330" is the code for S-PVA panels.
From what I've read, PVA panels are rampant in the A03 revisions, but a quick google search turned up a couple of different people getting Rev. A03 S-IPS panels first try. So, if you dont mind sending it back once or twice, the 2007wfp may still be worth a look.
