For years, people have been trying to create emulators that don't suck. So far, as far as I know, no one has succeeded. Wired has an article saying someone has created an emulator that will run software developed for any platform to run on any other, without noticeable speed degradation.
If this is true, it would be a miracle. But. I'll believe it when I see it. Until then, I have some hot beach front property for sale. Cheap. No worries about neighbors. No need for a hot water heater or night lighting. Priced to move.
