Arguably the HTC Desire should have taken the place of the Nexus One. It's difficult to call though as they don't say what a "feature" is. Is SenseUI, optical trackball, more memory, etc? Versus a trackball with an LED, noise cancelling microphone, etc?
Legend for style - yes. Single block of aluminium is just sexy.
Sony Xperia X10 for multimedia - yes. Huge screen, lovely. Shame the Samsung Galaxy S isn't out yet with it's amazing graphics chip.
Samsung Galaxy Portal is best for AR? Interesting about the AR on the homescreen. Didn't know that. Won't that suck power? Arguably there are better AR apps out there which can run on any Android device. So surely one with a good camera, big screen, and fast processor would be better? N1 or Desire.
