Here is a video from Google promoting some of their services to small businesses.

There is several areas were Google can help your small business computing needs and this video discusses several of them.

I have used several of Google's offerings and have found them to be pretty easy to use. The only one I have had problems with is Google Analytics which shows how much traffic your website is getting otherwise it has been pretty easy sailing.

As I do anything I discuss computer software, I highly recommend you try things out before signing up and of course check out the competitors and see what they have to offer.
