All those thinking of buying the new MBA, are you not concerned about availability of applications? Not all x86 applications will have an ARM alternative, yet.
Had access to a DTK, and know even more devs who have one. Even that machine could run essentially all x86 software just fine with Rosetta (including things like dynamically loaded plugins). Only thing missing is virtualization, but that's coming soon (Docker & Parallels are working with Apple).
