I'm running a 1:1 right now and holy cow. I know it's probably bias but I will say it's actually the best monitor I've ever used... I'm a developer so the balance between LOC on screen at full width is AMAZING. Color isn't fantastic on it but honestly I have two monitors flanking it on the left/right that are calibrated enough for basic print/photo needs.
The thing is - I'm still using it for things like PS and Illustrator because 1:1 works so well for complex applications like that... I just check color on a better monitor.
