New 24" LED ACD. It's actually replacing a new 30" ACD which will be going back to the local Apple Store shortly. Also ordered a USB and Mini Display extension cable so I can also plug my MBP in at the same time and still have the connectors reach my Mac Pro.
As nice as the real estate on the 30" is, it did turn out to be a bit overkill for my needs. Plus, the 30" I got had a minor issue where the left side of the screen was just a tad redder than the right. Color accuracy isn't critical for me, but once I noticed the color shift, I couldn't ignore it anymore.
At any rate, I'm digging the LED ACD. iSight and MagSafe are a nice touch, and the screen is much more uniform than the 30" ACD in terms of brightness and color to me. Sadly, the 24" really looks terrible due to the Apple Store lighting. There's virtually no glare in my home office, and the display looks orders of magnitude better.
EDIT: I noticed a bunch of you have soft LED lighting behind your setups. Where can I get my hands on some of those?
