I'm unfortunately running XP at the moment, although AmigaOS3.1 seems far more responsive on a processor 28 times slower (excluding all the optimisations an Athlon has that a 030 doesn't)
Sometimes it freezes on shutdown as well. And a couple of days ago it refused to recognise my profile, so I had to customise everything again. All probably because of a faulty line in the registry.
But it's still much better than a 32-bit shell and various applications kludged onto DOS.
