I really don't understand the rumor, nor would I understand Apple shooting at that price point. I mean, the 24" 4.5K display in the 24" iMac can be had for $1299, and that includes a computer.
So, I don't buy this a bit. Apple can clearly make a 24" display that would retail for less than $1000. If they don't, they're fools. If they make it and charge $2500, then we won't even stock the stupid things.
What the market needs is a $750 24" 4K TB3 display with charging. Everyone else can do it.
