At that point, why even include the charger? That would massively cut shipping weight like it did for the phone, and everyone already has a phone charger. I guess maybe they were worried some people would use a ultra cheap charger that can't even handle 20W reliably, but every OEM Android charger should have been fine with that for years, right?
I think this is part of why they don’t include chargers in the EU version of the Neo. If you have a charger from basically any time in the last ten years you’ll be fine with that.
