Well, I'm not going to all that trouble specifically to use a Mac; both the headset and the USB battery long predate the MBP. (And USB headsets have never made much sense to me in the first place, regardless of the machine with which they're used.) These are just the expedients I currently use, of the sort which I've found all portable machines to require.
The sine qua non of a computer's usefulness to me is its ability to support Emacs. While my experience has been that, all else equal, any portable machine is inferior for this purpose to any desktop, I have yet to find a better portable Emacs machine than the 15" rMBP. When I do find one, I'll use it instead.
If your "all Apple users are fashion-obsessed lightweights" proposition is susceptible to the white raven's disproof, this should amply suffice. (When was the last time you ran across an Emacs user who was either "fashion-obsessed" or "lightweight"?) But I suspect you'll prefer to explain away a white raven, than to reconsider your apparent confusion of reality with an "I'm a Mac, I'm a PC" ad.
