I massively disagree with the importance of swappable batteries. While I suppose there are people who are pretty happy hauling around a bunch of batteries with them, I haven't considered such a thing since camcorders were cool. A big part of keeping technology mainstream is to not require a utility belt. (n.b. I don't mind if they're user-removable for replacement once they've totally died, but this also seems to have become rather rare for what I assume are manufacturing reasons)
