Query: great product

it's changed my life :) now i can do whatever i want, and I don't have to arrange my schedule around a few shows i want to see.I bought the first replaytv available, back in 1999, for $1400 i think it was. maybe more. anyway, i noticed that for a while after i bought it, i watched more TV than ever, because suddenly i could watch anything i wanted to.then after a while, a few months, i watched less tv, because the novelty of watching CBS Sunday Morning on Tuesday night wore off. But now i just watch what i want to watch. And it's great for shows liek the simpsons, where there are a lot of little jokes. if you're watching and you think you missed something, just hit instant replay and watch it again. Or hit instant replay and then slow-motion and catch every single joke :)a great product :)
