While Google is best known for its leading search service, it has increasingly moved into other areas of the Internet, including in recent years music, cloud computing, mobile pay and mapping.
And many other things that hamper small website owners.
That being said would YOU buy from Google? I wouldn't simply because I have a business relationship with them (adsense/adwords/affiliate) and you don't mix business with other activities (google plus, shopping, email etc) unless you can weather unforseen problems and/or don't mind sharing a WHOLE LOT of personal info that may be used to squeeze you out of the small web property business someday too.
If I wasn't a webmaster/small business owner, getting things faster and cheaper is a good thing BUT there are some things I will pay more for from obscure places and/or mom-pop shops because I know the money is supporting a real family and not a big corporation.
