More than a year jimbeetle, probably coming up to two years or more.
I'm still seeing that layout after "testing" started on Saturday/Sunday with the "new" one.
I've tried random searches in various browsers again today and the "old" layout, for me, is still showing. Maybe it was a huge AdWords disaster for Google and they reverted immediately?
If so then there goes the myth that Search and AdWords act independently of one another!
