But they could do some filtering and traffic analysis to narrow things down, and only monitor the protocols and/or connections that they're interested in. Also, compression is an amazing thing... they could compress the data and archive it on a 500GB hard drive, which costs like $170...

With a computer, I'd be more worried about a key logger monitoring my every keystroke rather than my ISP maybe reading my chats.
But you have complete control over that. If your system is secure, nobody can install a keylogger, and if they do, you can detect it. With an ISP, you kinda have to blindy trust them.
