I recently got some clarification from Google on their offer of a free Google Mini Search Appliance. If you buy the regular Google Search Appliance they’ll give you a free Mini. The idea is that you might use the Search Appliance for your intranet and your free Mini for your internet site. If that doesn’t appeal to you they’ll knock the $3k off the cost of your Search Appliance.
If you do get a Mini, make sure you are up-to-date on patches. eWeek is reporting a security flaw in the device.
