I'm torn on this. The lighter weight is great, especially for women who have to carry them up steps. But I am not sure I see myself busting it down and rebuilding it to go in the backpack. I'd probably just carry it assembled. That's what I do now with my 24 pound bike friday. And I lock it up when I need to (through the chain ring and the struts). And my current BF is easy enough to knock down to size to go in a car and takes less than a minute. I don't think it will intrude on the brompton market, if that was the intent, because it is just too cumbersome. IMO the whole backpack thing is kinda pointless but the smaller and lighter bike is a win.
