Not the parent poster and no expert, but I'd probably buy a cheap random notebook from the store with cash and use it in free WiFis. Make sure to spoof your MAC address.

I mainly used Tor if I was on a dubious WiFi and was afraid someone was snooping on me - note that due to insecure exit notes you have the same problem there, too - or when something was blocked. But at least your employer doesn't see you use Facebook ;-)

Nowadays I use a server I rented in a different country as a SOCKS proxy which works well.

If you want to be anonymous towards the sure your accessing, I don't know of a good alternative. But many sites block Tor anyway now because people use it for spam or harassment.

Just a crazy idea, but if my safety needs were really high, I'd try to 1) buy botnet nodes and use them as a proxy or 2) build a ultra-low-energy Wi-Fi capable system (saw something commercial on HN the other day, forgot the name), set it up as a proxy, and throw it with a battery near a free Wi-Fi (coffee shop etc.).
