@TOI - I had edited the post before posting it, YES, in the tablet purchase example the other tabs mentioned are the "informational" searches (highlight processor name, right click search - highlight OS, right click search).
I find that people in front of me physically don't behave that way but to confirm another thing for you, the Big A "suggestions" of what other people bought will get the same treatment and again, Big A probably got the transactional query because I'm already there... why not click into them again?
When we say "transactional", the SERP for original terms contain prices, ratings and other data. Oddly enough searching for the components like processor and OS are less pitchy and more informy (fewer prices vs. more statistics to be exact).
And in conclusion... lol ... Big A ended that search reinforcing their position on the SERP. The other searches ended as well, both rewarding and reinforcing the manufacture's positions for those terms.
PS - Still haven't bought that tablet....
