I'm also still considering a nexus s4G my wife has one and it is great. Free is good too.
ICS is likely to work on the Nexus S4G too, and so we wouldnt be missing much. Just a dual core-processor.
That is just it, everyone gets so uptight about a processors clock speed. (I am guilty.) But I think optimization is the word here. If specs were the only thing important, then a Galaxy Note on GSM will smoke the prime everyday of the week and it is coming. Blackmanx says this device will be in all flavors, so bgr saying verizon exclusive? How long? (A droid nexus, I still can't believe it until i see it ha ha!)
I am still in my 14 days on Sprint. While the Prime seems like a geeky good time, the specs on the nexus S seems solid, and way more importantly, "optimized." A crap ton of geeks are bummed about the primes processor, who in their right triangle & nm mind isn't? Not a huge fan of those ICS icons, gawd awful if you ask me, but that is nitpicking crap. I think I may head in a check it out. It would be a good day to walk with a Nexus S and an extra two hundred bones in the back pocket
