You make absolutely no sense with your ports argument... I want a clean 1 cable design, but I also want usb ports on my display and firewire ports so that I can plug in my keyboard and possibly an isight camera if needed. The design of the ACD is perfect. 2 usb ports, 2 firewire ports. There is no need for anymore. I don't need 12 DVI ports, 6 component, a card reader, 12 HDMI ports, and 16 USB ports. I will just get a separate tv with receiver for more inputs. As for the ACD - it's over priced, obviously, everything Apple is technically overpriced, but I and many others are willing to pay the premium. Not only for the performance, but for the aesthetics. I love the look of the ACD I love how it matches my Mac Pro.
A new ACD will probably come soon - HDCP support will make a big difference for some, and no difference for others. The new generation S-IPS panels that were realesed are in no way superior to the ACD. Many of them have actually been claimed to be worse for graphics/video then the "yesterday" tech ACD's.
To the OP, Get a 20" ACD - you won't be disappointed. I wouldn't even think twice. You have 1 ACD already, get another, why would you mix and match?
if he gets a 20" acd he will be very disappointed...it will look completely different.
nobody wants 12 dvi ports or 16 usb ports or whatever it is you're saying. I don't want ANY USB ports or FW ports or anything in a display that is unrelated to DISPLAYING THINGS. You say it makes "absolutely no sense." and that you only want 1 cable...then go on to list all the cables you'd like to attach to the damn thing. apparently that makes sense?
a modern display NEEDS: 1 DVI port. 1 HDMI port. 1 power cable. if it has the circuitry to handle analog signals (apple displays lack this capability), then it also needs a VGA port.
I can't believe you're talking about iSight. You do realize they discontinued the firewire iSight over a year ago, right? Before you "switched," even, so I'm not sure how you knew about them in the first place...
as for the new S-PVA panels that have come out since the S-IPS panels found in the ACDs...they are better in every way. They have a higher maximum brightness, a lower minimum black level, wider gamut, more even backlighting, higher calibrated contrast ratios, lower deltas in color error, and lower latencies even without "overdrive" enabled.
The best panel available right now that is less than 30" is Samsung's LTM420CS, which has replaced S-IPS in the new line of pro Eizo displays that have hardware calibration.
The Eizo CG241W uses that panel, and it is $2400 dollars.
The LaCie 324 and latest dell (2408WFP) also use this panel, but they don't have all the bells and whistles. The dell doesn't have 12-bit internals.
The Eizo's new 30" pro display (just announced this month) also uses S-PVA panel (the CG301W). It will be considerably more than $3000 dollars and has 16 bit color processing internally.
Guess what else it has...two pointless DVI inputs.
