However, even at 24 inch size screen a pseudo “4K” screen (say, 2160×3840) the resolution would only be at about 185 pixels per inch. That’s not what any reasonable person would claim is a “Retina Display”.

And completely forget using that term on a 27″ or larger iMac screen. To get to a “Retina Display” on a 27″ iMac you’d have to have on the order of 3240×5760 giving about 245 pixels per inch. (At the typical screen distance that ppi might be considered a “Retina Display”.) However, that resolution (3240×5760) is not happening in the next few year — at least not on any iMac anyone can afford!

Could Apple do a 2160×3840 resolution display on a 27″ iMac? Maybe. It is possible to manufacture those resolutions today. Is it likely? No. That resolution is still quite costly. Last time a heard a quotation a few months ago it was still > $1,000 per screen even in huge quantities — and that’s just the screen cost. Add in all the other costs and you’re talking an iMac with an absolute minimum cost of > $3,000.

…I don’t care about Retina Display…. as long as it is glare-free and has Built-in USB 3.0

if apple can manage pricing like it has with the ipad with its mac, it will be a punch in the gut for ms.

the timimg of its flawed windows 8 couldnt be better for apple. the fruit is ripe for picking.

people will make the change this year, but it will not be for windows 8. nd as a long time windows user, i have no excuse anymore not power down my windows pc for the last time.
