I have owned couple of AMOLED screened devices (Zune HD, Omnia HD and Galaxy S) and i totally agree. Especially watching HD Avatar from Galaxy S super AMOLED screen is just amazing.
S AMOLED really does fix that sunlight problem, but the problem still is that Samsung probably is not going to give it to Nokia at least not just yet and the pentile screen problem where example Galaxy S screen is calculated to be about 653x392. It might not seem big of a problem and it kind of isn't but you do notice that Galaxy S screen is not as sharp as example N900's screen.

Those things in mind i would prefer something like S-LCD currently, but really i'm sucker for AMOLEDs and if Nokia manages to have one quality AMOLED screen for N9 i'm all for it.
