I'm not in the US, so mine will have a SIM slot which I don't need. US market is voluntold to forfeit the SIM slot, that means there's more room internally - is that just empty space? If so, shouldn't they get a bigger battery? Logistics be damned; this is a matter of principle - they give up something, they should get something. Leaving it as empty space is a slap in the face to them. Will be interested to see the teardown comparisons to see if they actually made use of that free space.
