It's useless to me was my exact first reaction. But I made a critical mistake, I moved my second NEC 2690Wuxi from my studio and put it next to my other NEC and tried lightroom with both calibrated monitors , I will never be able to go back to the CRT pallet monitor again. I can have 40 or 50 thumbnail that I can see for a change or a 24" view of my selected image. The side by side comparison is something to behold. This combined with Vista 64 makes lightroom so so fast. Take my advice and don't try this! It could be hazardous to your pocket book. Lightroom has finally arrived.
