On the first point I was specifically arguing on window management, e.g. the fact that FirefoxOS does not use surfacefinger is, as far as I can tell, minor, compared to the applications wonderful capacity to lock everything on just about every OS. FirefoxOS can indeed boot on 128MB (so the problem with Android is not really the kernel nor bionic), but if the applications do run poorly, what good does that make (yes, it does make some good, my previous post was overly cynical). My (admittely brief) experience with a FirefoxOS device with 256MB was precisely that surfing the web was quite frustrating. On the second and the third point I'll both agree with you and continue disagreeing. Yes, in some places a FirefoxOS is the only option. And yes, negligible is was a dickish term. But I was specifically talking about points on a graph. This doesn't make the project worthless (as I guess my post made it sound), but, IMHO, also means that the result will not fundamentally change the trajectory of the web and of the mobile market. One can obviously reply that giving someone their first smartphone should be enough, and that is a perfectly tenable position. On the specific example of those two countries, I'll happily take back my complaint.
