You know it's a bit unrealistic for them to have "all of the above" and still have the same price?
Not really. Most of the parts get cheaper every year. Most of the parts that have been listed as options are cheap. Apple have long since recouped the investments costs of the Touch in its current form factor. They've got room to tighten their margins a little. By this time next year, scale of economies will mean that they're raking it in again.
