I wonder how much effort will be required to port native applications to Windows/ARM. I imagine it won't be too onerous since both x86/x64 and ARM are little-endian. Excepting bits of inline assembly and use of compiler intrinsics I don't think it would be too difficult. I also wonder if there will be a FAT binary extension to PE/COFF, or if applications will have to have separate builds per platform.
