So what? N900 has multiple integrated processors inside. (430 MHz GPU, 600 MHz CPU and a processor for GSM module(?))

I think when people talk about "dual core" etc. they're really thinking in terms of SMP.
Most SoCs today have a single ARM core with additional hardware units to help with certain types of workload, but that doesn't make these SoCs "multi-core" in the same way that a SoC with two or more SMP-enabled general purpose ARM cores would be considered a "true" dual-core device etc.
Also the Android-based G1 had two cores on it's Qualcomm SoC - an ARM9 running a closed source real-time OS for the GSM stack (ie. phone functions) and a completely separate ARM11 for the Android OS and applications. The same SoC also had two DSPs plus media and video hardware acceleration units. Still wasn't "dual-core" though, as it had no SMP capability whatsoever.

No, don't fall for Qualcomm's abuse of the megahertz myth. They're pulling a Pentium 4 with their A8 stuff.
TI and Samsung licensed the Cortex A-8 architecture from ARM and proceeded to build their SoCs around it, tweaking the ARM design where necessary to suit their requirements, but it's fundamentally a Cortex-A8 at heart.
I do agree though that the ridiculous "megahertz claims" are leading us back into the dark ages of Intel vs. AMD.

Funny that it's called the "Glacier", I bet it won't feel so cold with dual core processors running @ >= 1GHz. However still sounds cool, so maybe it's warranted.

One big thing for the performance and battery life is that example snapdragon 1ghz and OMAP3430 are 65nm based while hummingbird, A4 and OMAP36xx are 45Nm.
