What about the processor and memory?
Nexus One: 1ghz Qualcomm snapdragon QSD8250
N900: arm cortex-a8 ti omap3430 600mhz

Ram memory:
Nexus One: 512mb
N900: 256mb

I've read that the "snapdragon" and "cortex-a8 omap3430" are very similar, but yet the omap3430 has a frequency of 600mhz whereas the snapdragon has 1ghz.
I've also read that although the omap3430 has 600mhz, it is considered to be more frequent powerful than only 600mhz. How? and about how much?
