The weight does not exist in a vacuum. It has to be evaluated in light of not just the other specs, but also the user experience.
Think about this: if the Honda Civic was upgraded to be able to do everything my SUV can, including towing, off-roading, cargo capacity, and overall comfort, but its size AND price stayed the same, would that not be considered revolutionary?
I guess that is a reasonable argument, but it was not at all what I got from your original post. Obviously all the features must be considered in concert under the umbrella of "user experience" but that is also nearly impossible to discuss as everyone's experience is personal and difficult to express. I don't think the iPad shaving off 200g is anywhere near upgrading a Civic to be able to do everything my SUV can for the same price and size, but I can see someone thinking that.
