windows xp/2003: barely need to think about it

vista: if i click enough buttons I'm sure i'll find something that looks like xp config

linux shell:if i read enough sets of instructions hopefully it'll make sense

linux gui: there's probably an application for it, it's probably fairly obvious what's what in it, hopefully it'll just work

mac: when i find the control panel equivalent, I expect it'll be in there and be even easier than xp
