The removable SD card its another thing I keep wondering about. I know 32 GB seems like a lot, but I also reminder when 4, 8, & 16 GB were "more storage than I can ever use". The Razr can go up to a 32 GB SD card out of the box, giving a little less than 48 GB total.
But, if ICS allows you to use external drives, or plug in a memory stick into the side of the Gnex, that becomes more of a wash too. Granted, an external stick isn't the most elegant solution, but it does solve the problem.
Either way, I'm getting an external battery pack. I've gone the battery swap route enough to know I dont like the down time or losing my place in a movie.
