Hmmm, nice and all that. But I was thinking slightly different.
If Google(NSA) has 100 people indexed. And they offer via via via TOR as super secret privacy alternative. After some time x number of people disappeared from Google, due too using TOR.
Who would be more prone for inspection by NSA?
So, my "How to keep private" suggestion would be a scenario like this:
Get generic laptop, using default installation and keep it like mister avarage. Perhaps even get some infections, be a general computer user.
Get a USB and use that for your portable internet browser from within hidden truecrypt storage. And yes I would also use TOR just to prevent those snooping locals.
Now look for open hotspot. Start your laptop for some basic browsing using the default browser. You need some alibi anyway. Now, also plugin your USB and start using the portable webbrowser or other tools you might need.
Afterwards, remove the USB. Although by using hidden truecrypt storage even the USB can be in plain sight.
