Well just how much are you into old or Classic Macs? This site really celebrates the history of the Mac. They even have a port of a Macintosh emulator (mini vMac) to the iPhone.
Of course, the emulator requires a jail broken phone, but it can be done. So I wonder how long it will be before it is ported to iPhone OS 3.0.
How about another article called Mac On A Stick? It allows you to have a “portable” Mac using the same emulator on a thumb drive to allow the running of an old Mac system in Linux or Windows or even various flavors of Macintosh.
See it here.
