What I think you have is you're in Australia and Janice is in America and the search data can not be possibly the same given totally different IP's and geological points. I don't think there is any way that each of you is going to the exact same server pulling the data for the request.
Plus I don't believe you both stated the question exactly the same.
It's not the computer...it's search engine queries based on yours and others search tendencies in your area mainly. Just like adds on the web. So it's mostly about your IP address.
