Why not both?
There are 3 models, MacBook, MacBook Air and MacBook Pro, why can't they diverge in focus? Sure, lighter is better, but that is if there are no trade offs. Some people accept the trade offs, other don't, but you have 3 product lines, why not letting them diverge on this question?
Also, you give people reason to have more than 1 Apple laptop, one with ports and great keyboard when ultra portability is not necessary, and the other for portability above all.
