Well, admittedly they are pretty limited in use, but I like to stay within shouting distance of good coffee at all times.
A Kyocera hand grinder and a pack of these things would fit pretty easily in a laptop bag, (or even a coat pocket) most offices/hotels/relatives houses have hot water available. I could also get a little parallel with a bunch of disposables, impress the natives, delegate, and not spend much time cleaning up afterward.
In the same situations a cone would likely add bulk and be fairly damp after use, and I think I would miss having a decent pouring kettle. A small french press wouldn't be very pretty given the grind capabilites of the Kyocera, and would add bulk/weight. The mypressi raises too many eyebrows during transport and needs constant gas cartridge ammo and cleanup time.
They must not let you out a whole lot, Tex!
