The Rezound should have ICS by next year so if you like ICS and you like the Rezound and can wait a bit for software then I see no reason to stick with the Nexus, in your case.
Some people will bear the troubles of the Nexus and wait for updates and ROMs to fix it -- I know I will, but some just can't and we are not going to bash you for it. Although I will try to convince you to stay with the Nexus anyway.
So I am flying out to Arizona with the girlfriend on Friday to surprise her grandparents for Christmas. They have NO idea we're coming -- I am really excited for this.
