[citation][nom]_TuxUser_[/nom]WINE do not emulate CPU, so running WINE on ARM will only manage to run ARM binaries made for ms-windows (this means some applications made for old ms-Windows Mobile), so the only way making WINE for Android to run programs made for ms-Windows x86 would be that the Android was running on a x86 based CPU.WINE for ARM ain't new, there has been a version for Nokia N900 for quite many years.[/citation]
Well, emulation could solve that just fine, granted the overhead issue is then potentially brought back and that might be an issue considering the already limited performance on Android devices. Also, there are a few Android phoens using x86 CPUs, so maybe it'll get somewhere anyway.
When you think about it, modern x86 CPUs are mostly RISC CPUs running CISC instructions that are translated into RISC micro-ops, so maybe the WINE for Android could do some more translation than just the Windows to Posix and it could be fine.
