Google has one successful product: search. Without search, most their ad revenue disappears. Android is successful but it's basically Linux + Java, arguably not a google creation.
All other google products are half-assed failures. Wave is a failure, plus is a failure, google glass will be a massive failure(I'd punch anyone who used it in front of me), scroogle is a failure, they can kiss my ass if they think i'd use any self driving thing from them, and on and on and on....
Plus the spying scandals, the daily new revelations of new details on the spying....I just don't think Google can sustain value if they continue acting like this. Google is not the nice guy from the early 2000's, they've become a monopoly on the WWW, a negative force on the WWW, with Matt Cutts dictating content and rules for the WWW and it's just fucked up now, they're trying to control links and they're making a mess of the WWW.
All in all I would not buy GOOG - just my 2 cents.
