My personal opinion is the screen resolution is the only thing the Nexus Prime has over the S2X. The S2X screen is excellent anyway. Sure, the Nexus has ICS but we'll have it soon enough. Now that I have seen the 1080p video result from the S2X I couldnt go back to 720p. On that note, having 8GB+ of music and photos loaded I need more than the remaining 3GB to capture video when needed. I have a 32GB class 10 just for that purpose. Nexus is also on another carrier up here which I would not want to switch to.
