Well, I have kind of "jumped on the train", since I do own a Micro-A1 with OS4.1. But I hardly ever use it, since the platform doesn't really excite me that much. It is a generic PPC box with none of the uniqueness and hardware-intimate hacking joy that my classics offers me. OS4 is an admirable effort, but the software I use is 68k-based, so I might as well run it on my classics instead of emulating it on a foreign architecture-based system.
