I do agree that Dropbox's wording is much friendlier, but I attribute most of the difference to Google having big plans (e.g., searching and sharing) and being careful that their terms will permit them. I suspect a big part of this is Google's intention to analyze your data to make it indexed/searchable (e.g., their 'search for Mt. Everest and get back your pictures of it' features).
