You need to understand the different LCD panels. Generally there are 3 types:
TN, S-IPS, S-PVA
- TN is the cheapest. Fast response time. Colour accuracy is so-so. There would be colour changes when viewed in an angle from side/top/bottom. Quoted viewing angle is 160 (from Dell). All 17 & 22in LCDs use this panel.
- S-PVA is from Samsung. Dell's 24in is using this. Pretty good colour accuracy. Very good black level (some-what important factor for photo editing). Colour changes when viewed in an angle from side/top/bottom.
Both the above panels will still work well for photo editing if you calibrate them... unless you are very-very fussy.
- S-IPS has the best colour accuracy (critical for video/photo editing). Quoted viewing angle is 178deg (Dell). NEC pro monitors and EIZO use this panel (more expensive than ACD, i think).
BTW, [some of] Dell 2007WFP and all ACD 20inch are using the same panel from LG-Philips. Dell 2007WFP has panel lottery --- you might get the S-PVA version instead of S-IPS one. All ACDs are S-IPS panels from LG-Philips.
I'd say get the 20inch ACD if you have the money. At least I would, if I have the money.
I think it's worth it... both for work and for the 'lan si' factor.

Colour quality as I always used to do printing production:
* When I use Mac with other monitors, I do not get accurate colour (this might be hard to differentiate).
* When I use PC with the usual monitors, it does the same.
* When I use PC with ACD, it does the same.
* When I use Mac with ACD, I get what I wanted on the screen.
You need to calibrate the monitors + PC/Mac + printers... everything. Contrast and brightness adjustment alone are not enough. Use calibration equipments for monitors like Pantone Huey, ColorVision Spyder2... etc... etc...
Macs are calibrated in factory already, so you get better colour accuracy. If you calibrate a Windows + other LCD, You'll still get accurate colours.
[I'm assuming your test was done without calibrating with proper equipments.]

Macfanatic,
You didn't pay all these premium for an ACD for dead pixels.
What I heard (rumours) in the LCD industry is that panels that pass the highest QC & no dead pixels will be sold as pro monitors, the rest are for consumers (cheaper).
No guarantees, but that's what I read somewhere in the net.
