When we launched the Google Mini last year, our vision was to make Google-quality search available to businesses everywhere at an affordable, transparent price. We believe that search is critical for every business, both for customers finding information on a public web site as well as employees finding documents within an organization. Users are now used to navigating information via search, so they tend to expect great search wherever there is information.More details over here.
Since our launch, we've strived to cut costs and continually pass these savings on to our customers. But, in keeping with our goal to satisfy our users, we've made this change without affecting the quality of the product or services we deliver. Customers will get the same great software, hardware, and support that they have come to expect from us, but at a lower price.
Over at the Google Enterprise blog they say it's a great search for your office, for the price of a "good office chair", a chair for the CEO that is.
