Nice job, Peter, nice software too. (Calcheck / Veripress, I guess?)
I think the debate over the 600 vs. 2000 USD displays is just pointless. Of course, my wife could transport the toddlers to the kindergarten with a Geo Metro, but honestly, it's more safe if she does it with a Volvo. The emphasis is on 'safe'. If anyone makes a living judging color day by day on a computer screen, he/she will not argue that a high-end hardware calibrated display with uniformity correction is a must.
My friend working next door got his shipment from HP some days ago. I just couldn't persuade him to invest in a high-end display, and finally he bought a HP 2475w. At first sight, the LG IPS panel looked nice, there was only one little flaw on the whole display area (it's not a pixel failure, but some tiny rubbish on the diffuser between the panel and the backlight). After the initial joy evaporated, my friend started telling me that he could see a 'verlauf' (gradient) of colors across the screen from green to magenta. I calibrated the display for him, and after that I took some measurements around the whole panel area.
I don't want to tire you with the measurement data, but the left side was a* negative, the right side a*positive, with more than 10 delta E's of difference between them.
Now I think this is pretty unacceptable for color-critical work. Okay, you can always place the graphics to the center 'sweet spot', but spare the price of a Big Mac per day, and you could have a real high-end display with perfect uniformity on your desk. I think I would choose the slim silhouette... :))
