there are no 32gb microSD cards yet...
this may make me sound like a dick but i have to say it. All of you are actually not talking about RAM, you're talking about ROM. ROM is where the actual android os is installed as well as all applications. RAM is memory used by the system to temporarily store variables and other data while running processes and apps. just clarifying.
unfortunatly it is.... the main reason you will see that the n1 is faster is the fact it has double the ram of the droid. 512 instead of 256.
they arent coming out and saying what they changed all they are saying is that they made minor tweaks to the cortex a8 architecture to acheive the higher clockspeed. Most of the info i have came from the FCC reports when a new chip is submitted for FCC approval.
personally i think the droid will be able to process more using less power as it has a seperate graphics chip where as the snapdragon does not.
