At the risk of being called a fanboy, it is not at all a given that an AMOLED will provide better battery life in all applications. AMOLED displays are also more subject to materials degredation, have shorter lifespans, and may be subject to burn-in. Most importantly, they are much dimmer than LCDs in sunlight.
In the end, the decision of which is better is a judgment call: a more durable, brighter, longer lived, less vibrant and lower resolution LCD may be preferable in some situations and to some people to a less durable, dimmer, shorter-lived, more vibrant and higher resolution screen. Something like superiority of a screen technology is not as black and white as you'd like to suggest.
Careful now - if you even breathe one utterance of admiration for anything Apple, he'll stomp on you with the "FanHammer"
I totally agree, and a lot of people just don't understand the finer details of the technologies about which they rave.
