Asking the dinky iMac GPU to drive a 4K screen will not lead to anything resembling an "IMPROVEMENT". In order for it to manage the kind of silky smooth scrolling and transitions we expect, it would need dual high-end desktop grade GPUs from ATI. Yay, my iMac sounds like a vacuum cleaner but them fonts sure render purty!Funny, I remember people saying the same BS about a retina screened iPad.I honestly don't get people naysaying IMPROVEMENTS.
Sure, I could choose to be like a toddler with ADHD going "I don't care if it's technically feasible or not, I WAAAAAAAAAAANT IT!!!!!!!! AAAAAARRRRRRGGGGHHHH!!!!!" and sit in a corner and pout until the world caves in to my arbitrary demands, but should I ever become like that, please do the gene pool a favor and shoot me in the head. OK?

There's this reason called cost. The iMac is a consumer desktop, not a money-is-no-object product.smulji said:I agree with you that there's probably no benefit of going full 5120x2880 retina but there's no reason why they can't go 4K (3840x2160)
Retina 4" and 10" displays, sure. Retina 15"... hot damn, that's one expensive laptop, but... OK. Retina 27"?
Here's an article from June about ViewSonic's 31.5" 4K monitor:
http://www.engadget.com/2012/06/05/viewsonic-vp3280-led-4k-monitor-hands-on/
ViewSonic reps say the VP3280, which will be marketed towards film studios, broadcasters, photographers and any other professionals in need of a compact 4K display, could ship by the end of the year, costing "about the price of a car."
Here's one from July:
http://www.kitguru.net/peripherals/monitors/harrison/4k-screens-are-1000-an-inch-but-not-for-long/
"4k screens are £1,000 an inch, but not for long"
The "not for long" bit doesn't translate to "in 3 months' time, 4K screens will be a cheap commodity".
