As far as I remember, that ad campaign backfired pretty hard when Microsoft released it's own "I'm a PC" ad.

IMHO that was the best ad Microsoft ever made. It was an obvious counter to the stereotype, but it made Apple users look like snobs, and Apple shut down its own campaign shortly after that ad.

As for the "scroogled", I think it mostly makes the impression that Microsoft is scared. I'm not sure if this campaign actually keeps more people from buying chromebooks than it does inform people that Google makes laptops.
