My Thinkpad Carbon X1 has a user-replaceable battery and is practically the same weight and size as a MacBook Air. So it is certainly not a compromise I agree with. The "disposable" label was a bit harsh, but there are other compromises in the MacBook Pro, for example the SSD, which is more prone to failure than other components, is soldered on to the logic board.
We may have a different notion of "user-replaceable". I'd only consider a battery that can be swapped without opening up the laptop user-replaceable. Soldering the components to the board is the same kind of trade-off: It saves weight, space and increases battery lifetime. You also compare the relatively new X1 with an outdated (though still sold) Macbook that was designed and built at a time when no laptop even got…
I believe the latest X1 Carbon weighs significantly less than a MacBook Pro.
