Quoting starkers, reply 14... or that the 2 second boot doesn't give you enough time to prevent Google inserting all sorts of advertising into your emails, both sent and received.
Mark I have yet to see even ONE advert from Google in my Gmail even after using it for years. Do you wear a tin foil hat when you use your computer?
kona, you ought by now to know when I'm just joshing.... er, the 2 second boot. 
No such thing even on the fastest PC. However, I discovered the tin foil hat was insufficient.
I now use a stainless steel saucepan... fits better and don't blow off like light-weight aluminium foil if there's a breeze. 
Google, quite frankly, is the least of my worries....
Same here: I'm more worried about the Pizza Hut spying on me to see which bits I pick out... and KFC sending unwanted home deliveries at 4 in the morning because I Binged 'fowl' when I actually meant foul.
However, all kidding aside, that Amazon thing is a worry... and very presumptuous to say the least. I do not use Amazon for purchases myself, but I know people who do... only when they NEED something AND have the money. This shipping stuff by guesstimates would see them broke or receiving 'pay up or else' notices. No, not a good idea at all, well not for the consumer. How sad, that profit generation comes above all else, including decency and respecting individuals privacy.
