Since other platforms are not quite there yet, I will be buying a data device soon, and I'm trying to choose between the two. Is there a special reason to get Nexus S over Nexus One other than the front-facing camera, which I don't even use on my computer? Gingerbread update is coming out for One, and it will have better SIP support, so I'm golden there too... The reason I'm thinking of One instead of S is that One has an actual GPS antenna, while S is limited to A-GPS.
