The only thing I'll miss about not having an SD card is have lots of storage for music. And I dislike using google music beta simply because I don't like the music player...powerAMP has spoiled me.
I certainly don't need 32 gigs of music or listen to a lot of it, but it will still be time consuming to go through and filter all that. Then it's still a question of how much space do you want to leave for videos and pictures.
