I have a wireless mouse that works via a USB dongle, and I use a USB headset for my Skype calls with my business team. I also charge my cellphone from a USB port, especially when travelling, as it's far more convenient to have one plug adaptor and my Macbook Pro power supply than carrying a plug adaptor and a multi-box everywhere.

At the moment, the two USB ports I have on my MBP are pretty much bare minimum but every now and then I find myself juggling peripherals.

If that works for you, then great!

You might consider the same cheat I use for charging, which is to keep a small but reasonably capacious USB battery [1] in my bag, and top it up via USB whenever I happen to have a port free. Since it's specified to fully charge an iPad twice, it can charge my phone several times before running flat, and a fully powered USB port can charge the battery itself in a matter of a few hours -- an overnight charge is ample. (And, hey, the only thing I ever plug in my phone for anyway is power, so it's not like I'm losing anything by not plugging into a port on my laptop.)

Another trick worth considering is, instead of using a USB headset, instead to use one which connects via the headphone jack proper. Mine is a Sennheiser HD558 with an aftermarket cable incorporating an Apple-style mic/remote module, but you don't have to get that elaborate, especially since the HD558 isn't designed to travel and does not do so well; for simple VoIP purposes, anything halfway decent will do, and serve the purpose of freeing up a USB port for things that a headphone jack can't do.

Why should one go to all this trouble just so he can use a Mac? There are many decent competitors out there that don't require these types of hacks (and for the record, I carry two USB batteries in my bag since there are occasions when I'm in the field for extended periods of time (24 hours+), but I certainly wouldn't be charitable to the idea of draining that backup power because Apple thought I needed to save 2mm of vertical space more than I needed the ability to transfer battery power from my laptop to my phone). That's the gist of the thing here. Apple people take using Apple products seriously and will go to lengths to make it work. Other people take their work seriously and will use the tool that best suits their needs. It's hard for me to imagine a MacBook ever best suiting the needs of a user that's more advanced than the casual Facebook browser just because so many sacrifices are made for aesthetics, and honestly even that market is a dubious target for the MacBook since the emergence of the tablet (for lighter casual users) and the ultrabook (for heavier casual users).

Do we care more about having the sexiest laptop in the airport or getting more productive time in? That's the dilemma one goes through when choosing PC v. Mac.

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.
