This display is going to be huge news once it hits the iPad and MacBook Pros.
Which is probably never. Those don't even reach the pixel density of the 2G/3G/3GS. 326ppi? That's already going to be pretty tall order on a 10" screen (the iPad currently stands at 132 ppi, assuming the form factor doesn't change we're talking about increasing the resolution by a factor of 2.5, pumping the resolution to an insane 2560x1920. We're talking about a resolution usually found on 30" computer screens here, and those things are still pretty much all between $1000 and $2000...).
The 13.3" macbook pro would have a 3712x2320 screen, the 15.4" would move up to 4200x2625 and the 17" would be sporting a 4000x3000 screen.
In 1995, the little point and shoot camera I owned could fit 36 pictures on a roll of film. My new little Sony point and shoot has an 8gb memory card. It can fit 1,500 pictures on a "roll of film," and the memory card is so small I could balance it on the tip of a finger. It also takes better quality pictures than any 35mm camera I have ever owned, has an internal GPS, and an an impressive amount of computing power, at least when it comes to image processing.
We are living in truly amazing times. Never say never :)
Both handhelds and desktops have been increasing in resolution, and decreasing in cost, for years. There's no reason for that trend to stop until all displays reach 'retinal indifference' at their usual viewing distance. I would not be surprised to see 4000x3000 LCDs in laptops in the next decade.
Never is a very long time. Is it really impossible that large high-DPI screens will exist in 5-10 years?
The verdict: slightly better crispness, comparable brightness, comparable color.
The industrial design of the iPhone 4G is superb compared to any other phone (or electronic device) I've seen. It's more comparable to what you'd expect to find in a watch.
I wonder what the effects of that are. It probably just makes the display a bit dimmer (if one were to use the same backlight).
Larger gaps alone implies dimmer, but this can be accounted for by having the pixels put out more light. Having larger gaps on a display doesn't mean it's dimmer, as the pixels have likely changed characteristics in the process of shrinking them.
