Anyone have experience using Rosetta Stone?

Especially at a more advanced level? I have tried the online demo (in German, since they don't provide it in Arabic) and found the vocabulary-building techniques interesting, but I am not sure how it teaches grammar or if it is useful for someone who is not a beginner. I have had one full year of university study and did an intensive summer program but have not studied for almost a year (shame on me!), so I am looking for an easy and fun way to gradually get back into studying.

Sorry to say, I can't offer any advice.

But I wanted to post a response so you know that some of us do check in here from time to time. It's been very quiet, unfortunately...

I check in as well...

I have used Rosetta Stone Arabic, but only for a short time, not enough to actually get any useful learning done. I'm not sure that the grammar will be stressed; I think Rosetta Stone usually takes the "natural" approach: learn by listening and speaking. I could be wrong, though.
