I don't think you're quite getting it.
When you do this in say... a well known Jersey website or an online auction site it suggests based on that it doesn't actually store the information (well when I last looked at the T&C's it didn't so if it has changed now then apologies).
Google are openly saying they'll store and use this information which is, surely, a very bad thing. From that data they can, in the future, aim adverts at you based on your history (i.e. phorm like crap), give you a blow-by-blow account of your browsing history, etc. remember even if you don't go to a website it's still being recorded.
I personally will not touch Chrome with a big stick.

They do aim adverts at you already.

Put down the David Icke book, take off the tin foil hat and step away from the computer. Because they're all after you!
