Summary: useful, but with limitations and a bit pricey
Comment: This can be quite useful to get the first feeling about the language as well as a surprisingly good tool for building up a basic vocabulary. However, it isn't a self-sufficient material for language learning - almost certainly you will need additional textbook(s) and/or teacher.
One, often noted, shortcoming of Rosetta Stone materials is complete lack of cultural context (the same set of pictures is reused for quite a number of languages). Still, the things are probably not as bad as they might be, since anhyway the main thing you will learn from this is vocabulary and not the skills at casual conversations (although the overrepresentations of some words, which probably are hardly used elsewhere but american english (e.g. "cowboy"), is a bit annoying). And apart from just having little use, such borrowed nouns usually also tend to be indeclinable in Greek!
A more important limitation, probably, is organization/ordering of pictures - beeing the same for a number of languages it is hardly the best for demonstrating the most important grammatical features of a particular language (such as tenses, declinations etc).
The bottom line - if you can get your hands on it, I would recommend at least to have a try. The official price tag, however, seems to be far too inflated for what these materials really contains - will not recommended buying without trying first and seeing, whether this really suits you.

Summary: Well worth it!
Comment: The Rosetta stone is well worth the money! I was very skeptical about this product. However, once I loaded it in the computer I was off to a running start. It is so much easier to retain the information with words, sounds, and pictures with an interactive format.
I highly recommend this product to anyone trying to learn on their own, or to supplement currant foreign language classes (like I am doing). I surprise my Greek teacher with extra words and phrases in each class.
If you want to learn a foreign language quickly, BUY THIS PRODUCT!
