The ULTIMATE Bag For X100 & X Series!

Referring to the internal dimensions of the Billingham v Domke (dimensions you supplied) there is over an inch or so difference in actual dimensions ... but your pictures of the X100 in front of bag are pretty much the same sized ratio to look at.

In reality, I doubt there'd be much difference in 'packed' potential either - neither are rigid containers - and whilst the Domke may not accomodate another extra shirt or pair of socks or so, it does look capacious enough for a camera and at least a couple of days change of light clothing.

I'd reiterate that this is only relevant when an 'essential' travel scenario (as usually accompanied by normal travel luggage) my camera is handheld, with only spare batteries in pockets, when shooting.
