@noiob That's what I'm feeling. Yet, there's surely no better practical option - gods know, Apple would be all over some means of shaving 100g off that tally. Aluminium isn't the last word, but it's essentially the sweet spot, for now.
The battery at least there must be weights available for. Probably not immensely heavy, but at that size, it'll definitely add to it all.
I wonder if a case & base unit could be added to levitate one.. ^_^ The world needs an antigravity iPad!
@porsupah hm, maybe half, a battery that size has got to be pretty heavy
