I have satellite, also, for TV. For computer, in my area at least, it's not very realistic or affordable: $599 installation on the satellite for computer and around $99 per month. There is also a cap placed on E-mail sent/received. For that kinda of money, I sure don't want a limit imposed on E-mail.

Much more affordable, and wireless: Broadband card. It's a small card that inserts in the computer either directly or via USB.
