Rosetta Stone is overrated...
Quite simply, this product is not worth the $300 - $400 that it is. It is alright because it does teach you some general concepts but overall it's not great. I found Japanese to be much easier than Chinese just because of the way the language is set up gramatically. It may benefit you more to learn a simpler language such as French, Spanish, ect. because Chinese is very difficult! Japanese is challenging but with the help of a dictionary and some online translators, it's not that bad. I think Spanish and French and other languages that are similar to English, will benefit more-so than a language like Chinese, Korean, or Arabic.
Why this fails to be a great language learning program, is because it does not offer English translations. I really feel that if they had an English translation page, my skill would improve much more rapidly. But for Chinese I need to look at every picture and translat it character by character from an online dictionary because you don't necessarily understand what the pictures are saying.
