This is one way of guessing:

case RUBY_PLATFORM
when /win32/
ENV['APPDATA'] ||
ENV['USERPROFILE'] ||
ENV['HOME']

else
ENV['HOME'] ||
File.expand_path('~')
end

Typical values:

ENV['APPDATA'] == "C:\Documents and Settings\username\Application Data"
ENV['USERPROFILE'] == "C:\Documents and Settings\username"

(This is from my 'preferences' lib.)

I have no idea what is right on OS X. I'm sure someone has thought this
through in more detail...
