I've had mine about a week now and I love it. Initially I was unsure as compared to my old Dell Ultrasharp it is noticeably glossier, and it feels a little bit too big to begin with. A curved version of this would work well. But now I've adjusted there's no way I could go back.
The colours are much more vivid, the blacks are amazing. You don't really notice the darker VA corners. I use 100% brightness to dodge the PWM, and frankly I could handle it brighter. It's not blinding at all.
I use mine for programming with my IDE 2/3rds of the screen wide and a browser in the final third. Both full height. It's glorious. I've also tried Farcry 4 at 2160p resolution on my GTX970 and it's absolutely beautiful.
The only unfortunate issue is my laptop, which I use for work, can't output 60hz at 2160p when it's hooked up to this. But frankly for office tasks it's barely noticeable dropping down to 30hz. The stand, as others have commented, is pants. But I've heard good things about replacing it with an Ergotron LX.
Deffo recommended, Phillips have got it right. And the price is the cherry on top.
