I tell my kids ( 9 and 7 ) "let's order a pizzaa and watch a movie". Yeah, Dad's a cool guy. Amazon tells me that the download will take 30 minutes to my TiVo. 1.5 hours later my kids and I are eating pizza and WE STILL HAVE NO MOVIE TO WATCH!!!!!
iTunes? I find a movie, place the order, and 10 minutes later we are watching an almost HD quality movie on my HDTV ( via my Mac mini ).
