I really don't get why you're saying that AMOLED techology is immature, there have been a lot of phones with AMOLED displays for more than a year now, and I've never heard about any problems apart from sunlight legibility

? All these issue you're talking about are fairly new to me. The fact that you once experienced a burn in problem doesn't make the whole technology immature

. Also, Apple not using AMOLED displays isn't really an argument against the technology. Bluetooth, LED flash, stereo speakers, camera, MMS and copy/paste aren't immature technologies either, yet still Apple waited an awful long time to use these technologies (or still hasn't used them). The iPhone has always been lagging in terms of hardware specifications. Not a big deal, but it's true.
More than a year is not mature. Apple have a reason I am sure, they just don't wish to justify it to anyone, nor should they need to. They are the ones doing the innovating, not the copying. You or I may not understand or know why Apple do or do not do things, but so what - they do enough to make every other copycat hardware and software vendor imitate them, so they are obviously doing
something (a
LOT of things) right.
You can debate it until you're blue in the face, but AMOLED
is a very new and immature technology - it is only
very recently that reasonable sized panels have been produced for a low enough price to warrant inclusion in consumer devices. Like it or dislike it, Apple are gonna go with the tried and tested route - they watch and wait to see how others fail, and how various bleeding edge tech either takes off or flops, and THEN they adopt the winners, not the newest, just for the sake of it being new or "better".
Let the other companies toy with the fandangled new technologies, and in time, Apple may or may not adopt the successful and reliable ones, based upon
needs not just
wants because the brainwashed public think because it's new and shiny, it is a MUST have.
It never fails to amaze me how people often completely miss (or ignore) the point regarding how Apple work. It is not all about the latest hardware specs, it is about how they can innovate and simplify the devices they conceive, whilst keeping the prices as aligned as possible with relation to the previous generation of said device.
This is SO much akin to the whole willy-waggling "my CPU is bigger than yours" that those ghastly PC gamer fanboys seem to think is important. You use an iPhone because you have made a concise purchase decision - beauty, simplicity and a staggering wealth of software available with just a couple of taps, almost anywhere you are, all in your pocket. If you want AMOLED then you can buy the rather awful Nexus One, but if you want the very best then you will buy iPhone. It's as simple as that, it really is.
There is perfect logic to this, but if you cannot see the logic, then I cannot explain any further without wasting my effort in doing so. Anyone with a designer's mind who truly and completely "get" what Apple is all about, know that it is something which you cannot completely explain to other people... something which is either simply understood, or learned through gradual usage of their products and services. Emotional connections to objects is the key with Apple products, and believe me, they know every trick in the book to help you enjoy using them. If you don't "get Apple", then no amount of explaining or forum posts are going to change that for you - you're just going to be looking at cold hard numbers and component specs, comparing them to other devices, regardless of manufacturer and software/features.
The best designs are the ones that appear "undesigned" - in other words, the designer has worked and worked, refining the product until absolutely everything that is unnecessary has been removed and trimmed down until only the absolute essential components are left. For instance, look at the sleep indicator on the iBook/MacBook Pro - you wouldn't expect that to be noted as a "feature" which tells how clever Apple were to think of it, it is just conveying a message when the message needs to be conveyed, and at any other time it simply vanishes. You don't think of the hands on a clock as "clever", they simply point to numbers and tell you the time - they do what they need to and no more, but also no less.
Something that is to work well and without fuss and frustration on the owner's part, has to be "undesigned", so when thinking about it, your emotions tell you "why would it be ANY other way", by simple instinct. I am struggling to carry across what I am trying to say here, because it is something you just feel without consciously considering it most of the time. If you really don't "get it" then you can't have it explained easily.
