Rosetta Stone

ok, my, ahem, friend, is looking to improve his, er, i mean her spanish skills and, uh, isn't looking to pay 'retail'.
can someone help my friend out to a place where they could,um, test drive the software so they can figure out if they should buy the full package? in a way that someone that is sort of computer illiterate would understand how to discover the software.
the interested party only knows how to use limewire for discovering stuff so torrents and whatever newfangled stuff is out there doesn't make sense to him. i mean, her.
