of course we can agree on that

i just want to point out one more time:

the scale is everything (as i've stated time and time again).
your local grocery shop can't really abuse what little data they collect. google's insurmountable amounts of data about individuals is on a completely different level than your nice little toilet paper example (which made me realize you didn't understand the issue at all, hence i'll stop arguing about this any further).

you may call me paranoid, but i see just too many possibilities for this much data to be abused.

if you think giving up a "little" privacy (which in fact isn't little at all) for the convenience of the google services is a fair trade, fine. i don't think it's fair at all.
