I like eInk and AMOLED screens, but the prices, sheesh.
I guess I'm just too "multimedia" focused of a person (being an A/V nerd and video editor by profession), but... eInk is completely uninteresting to me. Yes, yes, it has super-long battery life, but I want to be able to have, you know, color pictures. Maybe a video or animation here or there? It is the year 2010, after all. Besides, one of the
BENEFITS of reading at night on my iPhone's Kindle App is that I don't have to turn on the lamp on my nightstand. I just keep the Kindle app in "white text on black background" mode, and it is crisp, easy to read, and doesn't wake my sleeping wife up (which is worth more than anything, really).
AMOLED screens are nice in good lighting conditions, but people
way downplay the glare and color accuracy issues on them. The reviews always say "OMG, the AMOLED screen looks BEAUTIFUL!!! It doesn't look so good outside, but OMG it is SO BEAUTIFUL!".
First off, AMOLED screens just look super-saturated to me, but that could be the fact that I spend my days surrounded by high-quality, color corrected IPS panels. For "normal" people, the glare issue is even more important for a mobile device. It seems like the same mindset that lead to all laptop screens having these crappy glossy coatings on them. They look great in the store under controlled lighting conditions, but once you get out in the "real world" trying to use it on a city street or on an airplane... Give me my old matte screen with good viewing angles and the ability to use it outside or in front of a window, please!
I have a friend at work who has a shiny new Google Nexus phone. It is nice and all, but if you take it outside here (especially on a clear winter day here, with snow on the ground) and hold it side-by-side with my iPhone, the difference is literally night-and-day. Her Nexus is almost unusable under bright conditions with the screen brightness at maximum. My iPhone is dim, but still perfectly legible, with the brightness at 50-60%. The AMOLED on the Zune HD is even worse, from the couple I've seen around.
I just think that AMOLED has promise, but needs a few years to mature.
