Incredible's seems to already be fading out. As soon as Verizon's butt-buddy Motorola launched the X/Droid 2, Verizon didn't even have Incredibles on display anymore. Between the Launch of the X/Droid 2 and the AMOLED shortage, the Incredible will probably meet an end of production very shortly. As someone else said though, owning an Incredible is certainly cool because they are pretty damn rare. Verizon WAY undershot the amount of Incredibles they would need, and while demand is very high, the amount of supply going out is very low (and most people at this point are switching their order over to the X or Droid 2 anyway). I'd say when it's all said and done, Incredibles will definitely be a very rare phone to have (I for one, have never even seen another Incredible out in public); people ogle and ask about my phone like mad when they see it.
And as for the difference between AMOLED and SLCD? It's like the difference between Plasma and LCD in that typical ignorant consumer "A" goes into a store and sees the LCD next to the plasma, notices the LCD is substantially brighter, and therefore concludes it is a superior product. Now, anybody who knows anything about picture quality knows Plasma absolutely blows LCD (and even most LED-LCD's) out of the water once you get them home and calibrated. The simple matter is, most people don't even know what a good quality screen is SUPPOSED to look like, let alone be able to ever recognize one. Hell, many consumers are so ignorant and uninformed they can't even tell the difference between SD and HD.
There is a substantial difference between AMOLED and SLCD; and I'm not just saying that because I have an Incredible. My dad has the X (TFT-LCD, but comparable to SLCD), and the image on my Incredible is so much more natural, colorful, smoother, and appeasing to the eye (not to mention those epic black levels). The X has a brighter screen and handles sunlight a bit better yes; but as far as actual natural picture quality goes? It's not even a question. I have personally never seen an SLCD, but I know it was designed mainly to be as pretty as TFT-LCD just with less power consumption; it wasn't designed to outdo AMOLED, which is considered the near future for HDTV's because it is just so damn pretty.
AMOLED is still a superior technology to SLCD (which comes with every inherent drawback of LCD, extra "S" at the front or not); and I am having a hard time fathoming all of these people saying the difference is minimal or non-existent. If production of the Incredible ever did switch to SLCD, it better also mean a switch to a lower price.
Only problem I can see is in the near future, replacement Incredibles if one breaks may be non-existent.
