Yes, it does.
I've yet to see anyone max out a notebook. Use it so strenuously, push it so hard to its limits that it disappoints. Today's worst notebook are quantum leaps over what were state-of-the-art just a few years ago. Today it's all about form factor. It's all about weight. It's all about height. It's all about a retina display. The rest is just processor speed mumbo-jumbo chest-pumping.
This conversation is just like the M3 guys vs. the 328i guys over at the BMW forums. 500 horsepower engines to go 20 MPH in school zones. Power that's there for show, actually never used. The RMB is different where it matters most. No one redlines a notebook. It's there for email and browsing, no one uses it for much more.

You words do not change my mind. I look at a laptop as an appliance to get thing done and the MB is too much of a compromise for the sake of thinness. Apple "experiment" in a fanless laptop come at a deep cost in my opinion. But it give Apple fans choices. I take my loaded Air any day for my purposes.
