Small proxy for enhanced security, privacy and ads filtering

I prefer to use small netbook over desktop pc for light web browsing at home. It's very comfortable but I need something to filter out advertisements.

Squid is rather overkill, so I checked two other solutions: Polipo and Privoxy.

Both of them are easy to configure, offer interesting features (really check it out!) and are constantly updated.

I decided to stay with Privoxy for now because I have more experience with it but I am very curious about Polipo.
