FWIW, I've been using the Galaxy Nexus and it's a rock solid combination of Samsung hardware and unadulterated Google software, above and beyond the iPhones I've used in all parts of the experience except battery life (it lasts as long as an iPhone 3GS did for me). This is in contract with the Sprint-modified Galaxy SII that I also got to use, where the software was messed with for no good reason, and the capacitive buttons would sometimes become unresponsive.
