Apps can take up a lot of space. You'll still be fine with 8 for now, but I'd want the future-proofing! For instance, if "real" GPS software arrived (with the maps pre-stored) that's got to gobble storage.

(And you may find yourself watching movies or video podcasts more than you expect. With an adapter, you can deliver movies and TV shows to a regular TV from your iPhone.)

But if it's a question of TWO phones vs. one? Take two!
