some folks call it a Kaiserbox

It sounds too good to be true. A device that lets you watch the content from your home TV on your computer anywhere in the world. If I had one, I could take my laptop to the beach or to a fun food festival and still keep up with the local shows from home. It's called a Slingbox. Their website explains it better than me. I would like to hear from anybody who has one. Do you love it? Should I start saving up for one?
