Meanwhile, the xerox lisa had a DPI of 90, while a regular macbook has a DPI of 110. http://www.mprove.de/diplom/text/3.1.8_lisa.html http://members.ping.de/~sven/dpi.html

Yes, but the Lisa cost about $22,000 (adjusted for inflation). A regular macbook costs $1000.

Just curious, how did you do the inflation adjustment?

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 2560x1…

30 years ago, you were lucky if you had a 300 bps acoustic modem. 20 years ago 9600 bps was considered state of the art. I am writing this while sitting in Peets in Los Altos where I have a 54,000,000 bps wireless connection, not to some local BBS, but to this much larger, almost unimaginably (at least it would have been to me in 1980!) complex structure, the internet. In 1995, the little point and shoot camera I own…

There clearly is lots of innovation going on, but 54 Mbps wireless hardware was introduced over 11 years ago!

Furthermore, AT&T's DSL speed has only exhibited a .15 Mbps CAGR over the past 5 years to its current peak of 6 Mbps. Comcast's average cable internet speeds were 6 Mbps from 2005 to 2007, until they jumped to 12 Mbps in 2008.

Can't wait for the future...

It seems to me that the black gaps are bigger. I just did a back of the envelope calculation, using the photos he posted and it looks as though black gaps take up about 30 percent of the space on the first and second iPhone while they take up about 40 percent on the new iPhone 4. 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).

It definitely seems dimmer to me, especially when it autodims, compared to my 3G

I have found the opposite. Especially in bright daylight.

Having queued for 7 hours yesterday to get my iPhone 4, I can confirm that the display actually exceeded my expectations. All natively rendered text in controls, etc., looks like it was printed in a magazine. This display is going to be huge news once it hits the iPad and MacBook Pros.

I can't imagine that Apple would have gone to the trouble of giving this kind of display a name & logo if they were only intending to use it on one product.

I'd guess using something like http://www.wolframalpha.com/input/?i=inflation+rate+in+US+fr... to establish a mean rate and then using "compound interest" formula?

I've heard the cost in lcds is far more about the size of the display vs the resolution. Ive seen replacement lcds for projectors, very small lcds with very high resolutions for faily cheap prices.

Desktop monitor resolution is still at ~100dpi because no desktop OS has solved the scalable UI problem satisfactorily. The OSes have some attempts at support for UI scaling, but none works well enough to run all of the popular software decently at 200dpi.

Contrast that with iOS. I only have a handful of non-built-in apps, but they all work perfectly on my iPhone 4, none look worse, and all but the graphics-intensive games look better. I haven't seen any reports yet of software that doesn't scale properly on the iPhone 4.

Apple's tight control of the iOS software marketplace may be a key factor in this success. They may have privately checked a large amount of the software submitted to the app store, and rejected apps which failed to scale properly.

It's far simpler than that:

Company's rarely change the name of a well liked product. Consider a 1976 Honda accord vs a 2010 Honda accord. They are vary different cars targeting different markets but as long as people think product X = quality the name tends to stick around. (1976 68hp ) http://upload.wikimedia.org/wikipedia/commons/3/3d/1977-1982... (2010 177-hp to 271-hp on a v6) http://automobiles.honda.com/accord-sedan/exterior.aspx

On the other hand, consider PowerBook--a strong brand since the early 90's that was still phased out.

Having been named after the PowerPC architecture probably accounts for that one.
