When I got my first new PowerPC, it was a toss up between a 6100 or a 6200+ethernet, the prices were very similar.

I choose badly and went for the 6200 and ever since wished I had the 6100 especially when they got MkLinux going on it, and somebody had managed to load AIX programs on it.

Ironically, now the 6200 is flying with Debian Sarge, and the 6100 is still stuck with MkLinux.
