$249 for an 8gb sounds very realistic. I just hope it has GPS capabilities. If it does, I'm game. If you are smart with what you listen/watch/download 8gb is not too horrible. Sure you got to be economical about it. I use the google music 3rd party app that lets me stream my music collection. I stream my movies through Plex.
I know it would be easier to have more storage, but to save 100 bucks and get all the great features of IOS 6.
All that being said, having GPS is a must. I'll keep my fingers crossed that it does.
