It's ridiculous they don't include either and I say that as someone who doesn't actually need either, really.
But it's nice to be able to backup my DCIM folder to the SDcard and then sync that via a network share on a regular basis, especially if I hadn't got adb enabled and/or I had a smashed screen?
It also allows me to just wipe my internal storage anytime without worry because I don't record many videos and photos take up fugg all storage with a 3.2.1 backup plan.
edit: What's the point of excluding, a headphone jack too I feel is the real question.
