If you told us twenty years ago that, by 2007, there would be a pocket-sized device that could make wireless phone calls, take pictures, play music and show movies, we'd probably get a little dewy eyed at the techno-futuristic possibilities. If you told us that device would also be able to replicate the games of hundreds of upright arcade cabinets, we might very well have exploded with anticipation.
So far, the efforts to port the ubiquitous Multiple Arcade Machine Emulator to the iPhone have had pretty limited results -- anything more complex than Pac-Man or Q*Bert reportedly runs into some hefty performance problems. Still, we can't help but imagine the possibilities that will come with some more development time. After all, just look at how far we've come in the past twenty years.
