I Want A Retina Display Monitor

After approximately a week with my iPhone 4 I have truly come to love the Retina Display.  It is such a fantastic display.  As I pointed out in my iPhone 4 review, everything is much crisper, sharper, and just flat out better looking then any previous iPhone or phone I have ever used.  Now, I currently use an Apple 30″ Cinema Display with my Mac Pro and I love it.  However, since getting the iPhone 4, I can’t help but notice the difference when going between the Cinema display and the Retina display.

The smaller Retina display looks so much better then the Cinema display, especially when it comes to text and graphics.  The iPhone 4 displays 326 pixels per inch on a 3.5 inch display at a 960 x 640 screen resolution.  Imagine the possibilities.  Screen resolutions on a 20, 24, 30 inch monitor.  It would be insane (and would look great).  Even being able to build the technology into smaller displays such as 13″ – 17″ on the Macbook Pro line would be awesome.

As far as I can tell this type of display can be built.  It’s just a high density IPS display.  The problem lies with cost.  I would love to be able to purchase a monitor using the Retina display technology.  However, I would like to be able to keep all of my body parts to afford it.  My question to you: how long until this technology is available to the consumer market and how much would you be willing to pay?
