While I would love to have the 24" HP 1920x1200 glossy monitor I use at work (which I only use with a unibody MBP) replaced with this, I'm not really interested in this for my personal use for a number of reasons:
* Resolution is a step backwards from the 30" 2560x1600. I prefer 16:10 (or even 4:3) because I value vertical space more than horizontal as I'm mostly viewing vertically flowing documents (web pages, code, etc). I can live with this since the vertical resolution is better than the monitors I currently use.
* Glossy display. I prefer matte, but I can live with this.
* The deal breaker: only one input and its Mini-Displayport. At home, I have three different machines I want to use the monitor with. Two have DVI ports only, and I bring my work machine home which has Mini-Displayport. If this had two HDMI ports in addition to Mini-Displayport it would be perfect. AFAIK, Apple has never made displays with multiple inputs, though, and that's disappointing.
If there were some sort of KVM that could handle my scenario (and reliably at that) that would be nice, but I'm sure such a device would cost several hundred dollars at least, at which point I might as well spend a little bit more and get a 30" 2560x1600 matte display (e.g. Dell 3008WFP) that supports multiple inputs.
Though, for someone who only has a single Mac (with no plans on ever using more than one on the monitor) that is new enough to have Mini DisplayPort, this seems like a nice option. Magsafe connector is a nice option for laptops, and sound going through Mini Displayport is kinda cool. The price is not bad, either; at least at the moment it seems to be competitive.
