This reminds me of the BadAstronomy writeup about Jobs and the resolution of the iPhone 4: http://blogs.discovermagazine.com/badastronomy/2010/06/10/re...

Ya, I was thinking the same thing.

At 440ppi, this seems like overkill, considering someone with 20/20 vision only needs around 300ppi for things to be acceptable.

I was hoping with the retina marketing blitz, Apple would put the density comparisons to bed and we could start thinking about displays with wider colour gamuts, wider viewing angles, better outdoors performance, 3D, mini projectors, etc.

I understand hard numbers like ppi are easier to compare between and display in huge letters in a BestBuy flyer, we called them 'checkbox features' at a place I used to work at, but at some point they distort the overall quality of the product. For example, the Pentium 4's clockrate and megapixel ratings on cameras are cases of a checkbox feature actually decreasing the quality of most products in the market.

So why is it that we're still stuck with 1920x1080 on our desktop displays? And don't even get me started on laptops!

Maybe you haven't been looking hard enough? I've been using HP's 27"2560x1440 for months hooking up to my lowly macbook air 11. Cost ~$660, worth every cent (for comparison, brought the first Dell 24"1920 display when it first came out for ~$1k).

For laptops, the (pretty strong) rumor is that new macbook pros coming out in summer will be much higher res, potentially up to double current resolutions.

For current laptops, the macbook airs and similar PCs currently have the highest "usable" resolutions. The sony vaio z and p has the highest resolutions.

Yield, if I had to guess. Manufacturing a 24" 16:9 300dpi screen would lead to a resolution of around 6259x3543. Now consider the manufacturing waste due to defective pixels in existing screens at current resolutions, raise that rate by a few orders of magnitude to account for the need to fit more pixels of a higher density (== increased defect rate by itself) in the same physical surface area (== increased chance of a single piece of substrate containing too many defective pixels).

Finally, consider the power consumption of the 3D card required to drive a modern game natively at this resolution

For the longest time, operating systems didn't really work in High DPI. At Apple, a lot of the designs relied on pixel art, and scaling it looked terrible. There are breadcrumbs for scaling in OS X that date back to Tiger or Leopard.

This is one of the reasons why the iPhone4 straight up doubled the resolution even though it made for kind of a wacky display resolution (as opposed to 1024x600 or something more standard like that)

Mountain Lion is supposed to finally get all that HighDPI stuff right though, according to the rumors.

I'm only really familiar with the Apple side of things though, maybe Metro has similar design considerations in mind.

Earlier quoted context omitted.

That would affect the user experience of the device. How would you hold the device? How would you play games? HTC Sensation is an whole-screen device, but the user experience is really bad. I prefer iPhone 4/4S design any other day.

The bevel could be virtual - painted on by the OS or application but not accepting touch inputs. Perhaps even custom to the user preferences. It could go away for certain uses cases, like full screen video. It could even have function buttons rendered on it that are context dependent.

Sure, this might work. But the extra pixels needed for the bezel will consume battery with current technology. Also, a new kind of proximity sensor have to be developed for these use cases. It will be really annoying to set the virtual bezel manually all the time.

How about making batteries that can make your phone run for more that 8 hours straight now? I'd buy the phone that would give me a week of uptime (and that is not a 3310).

The Razr Maxx has incredible battery life, not quite a week of uptime but a good 3 days of normal use.

Not on AMOLED. Remember that AMOLED does not use any power to display blacks.

Unfortunately, you have to look pretty hard. The HP, a Dell, and Apple's Thunderbolt Display are the only three proper 27" displays on the market apart from some significantly higher-priced options. Nearly everything else from every manufacturer is one-size-fits-all 1080p, your only choice being how big the pixels are.

Back in 2000 I was using 1920x1200 on a 12" laptop. I was running both WinXP and some version of Ubuntu, and they looked fine. Every since then I've had WUXGA screens and displays, until very recently when Dell and Lenovo decided to bail and move to the 1920x1080 short screens.

It's a step backwards.
