@TheMadScientist - I have never noticed a title change on my site. I have noticed a long time ago that google would change the title if it thought that the user was searching for my business rather than general products and it would change the title to the business name.
This is not to say that they don't do it. They seem to be able to show you what you want to see. Plus they may well change results that I don't monitor
