I have the Rosetta Stone in Italian. I bought it off groupon last year at a great price, which I now don't remember What I paid. Only problem is I use my i pad and my daughter uses "our" laptop for school. The RS version I purchased only works with a regular computer, so I haven't used it as planned. I'm not sure if newer version are i pad adaptable.
Who knew it would be so hard to negotiate sharing "our" laptop with a teenager? (She's in a really tough school with lots of homework, not just goofing around on it).
Oh, and check with the library. Our local one didn't have it last year when I asked, but they did say they were looking into ordering some of the languages.
