I didn't realize they'd hidden cached pages this way...but here's a data point on human behavior that may be non-optimal for Google: So, yesterday, I searched for something on Google, found what I wanted, went to click Cache and it wasn't there. I didn't think to go mousing over the page...I instead did what any red-blooded search engine user in a hurry would do: I copied the URL, pasted it into Bing, and viewed cache from there. 0_o
