So it seems most people use it for sports. I'm not a sports fan, so that's probably why I don't get the appeal. A few years back I did get into watching football but I had no problem recording the games. It never made any sense to me why people cared if they were watching "live" or not. I actually preferred recording the games because it allowed me to skip the commercials. I've since stopped watching football for the most part.
Another problem I have with PIP is I'm easily distracted. I'm not a multi-tasker at all. I can only really focus on one thing at a time anyway. My wife can attest to this every time she tries to talk to me while I'm watching TV or surfing on my iPad and I don't hear a word she says.
