I'm interested in getting one for various reasons, but I don't know a lot about them, so I have questions. 1. Do they impact browsing/streaming speeds? Unless you're twitch gaming, you won't really notice the difference unless you connect to a horrible server. They will increase your latency slightly, but you won't notice it doing normal browsing/streaming. 2. Does it work to circumvent blackouts? Depending on the VPN service. Yes. Right now, I'm somewhere in Germany..... now I'm back in Milwaukee. 3. Are you less susceptible to virus attacks, or does that have more to do with security software? You're still susceptible. Your computer is still connected to the internet, and if you're browsing sketchy sites or downloading and installing things your vpn won't protect you from that. 4. Does anyone out there play Strat-O-Matic via netplay with a VPN? I ask because there have been some security software programs that have interfered in the past for me. Can't help you there, but a VPN is not security software. It is masking/encryption software. 5. Benefits are anonymous browsing, more secure when using open wi-fi, and..........? You've hit it right on the head. That's pretty much the two huge benefits. http://lifehacker.com/5940565/why-you-should-start-using-a-vpn-and-how-to-choose-the-best-one-for-your-needs
