None of Google's logos seem particularly good or interesting to me. From a business standpoint, pre-school style design is probably the image they want to portray; that Google is very simple and easy to use. If you're going to criticize the logo, criticize it on it's merits as a logo: giving the first impression you want to foster in it's users. Not just whether or not you think it looks prettier.
