vi or emacs? Not going to happen, these are among the most portable software that exists.

About Chrome or FF that's only depends on the developers who use the product, I doubt that Google will ever target Mir, actually I believe that the GTK+ backend could target Mir and then boom, all GTK+ applications will then run on Mir, including Chrome. If Google ever comes to target a system with their browser this will probably be Chrome OS.

Firefox is another beast, but unless there's a decision to abandon Linux altogether there'll be devs working on it, or on iceweasel, it's Debian cousin, and this will probably run/compile in every Linux (and BSDs?) out there.

About 3D this is a shit area, I believe this move signals that Canonical will try to sell ARM computers in the future, there's a know lack of free drivers for GPUs in the ARM world. To see what I mean you'll only have to search for the Raspberry Pi "open source" GPU drivers debacle to see how things are going. This is not a criticism of Broadcom who has it's trade secrets to protect, but there the situation is far from perfect and always will be.
