I use Pegasos II G4 as my primary system. I do most browsing, ircing (thru ssh connection) and coding on it. The system is triplebooting to
MorphOS (development version),
MacOS X 10.4.7 and
Debian/GNU Linux, but I use MorphOS 99% of the time.
I also have Pegasos I running Debian GNU/Linux 24/7 and some Windows XP PC boxen. The Debian system is used for IRC (ircii), mail (pine), gateway/firewall (natting my adsl connection with ipmasq), file server (samba) etc. The PC is handy for some browsing that can't be done using IBrowse, and some gaming. I could do browsing on the Debian side aswell, but I only use linux thru console.
So, I use four kind of systems: MorphOS PPC, Linux PPC, Windows x86 and Mac OS X PPC. It's "tool for the job" kind of thing, I don't feel terrified for using the Windows XP machine when I need to, but I feel most confortable on the MorphOS. It feels much more responsive than any of the other systems, anyway. :-)
This is perhaps more alternative than most, but I don't consider myself "retro user".
