If the phone form factor itself is identical and the only upgrade is cpu/ram i'de try and get one. The amount of time between closing and opening apps currently drives me nutty. Especially if i've gotten a postcode off the web and i'm trying to open Maps to put it in.. That always seems to take just long enough for someone to interupt me and forget the damn thing. And notes takes too long to become usable too. If the cpu/ram upgrade makes these things closer to instantaneous (And faster webpage rendering etc) that'll do me fine.
