I picked one up on New Years Eve for use with my mini and so far I love it. It is easily the best monitor I've used. Not only does it have a great image, it looks great just sitting on the desk.
So far, no issues with it at all. I saw the "blacking out" thread over at the apple support forums and was a little worried about it but so far I haven't seen it with the mini.
As mentioned, the cords are short and I even had an extension ready to go but it turned out they are just the right length for the mini that sits just in back and off to the side of the display.
The input options are limited and this could be an issue for some people. In the past I've only had my monitor hooked up to the computer and I don't see that changing so I can't see this as ever being an problem in my situation. If you need more inputs, it could definitely be a problem.
I was a little concerned about the reflective screen too but the room it is in doesn't have any direct back lighting so it hasn't been an issue at all. If you are in a bright room or have back lighting this could be troublesome though.
I find the 1920 x 1200 res. to be perfect for a 24" display. I wouldn't want (and wouldn't purchase) a higher res in a screen this size and I much prefer the 16:10 to the 16:9 that is becoming so common now.
