That's good to know about cables and housing. Considering the price it's a little disappointing the bikes don't come equipped with the good stuff, but I suppose that could be said of any bike that comes stock with Avid BB7s or other higher end mechanical disc brakes.

Another concern about the Brompton I didn't mention is the tire clearance. Caliper brakes make a lot of sense with the fold, and the suspension does do a good job of taking the edge off rough pavement, but with fenders on tire clearance is fairly limited. When it's rainy and slick out a bigger contact patch can be nice.
