Sounds to me like it's just an upgraded box, you can record 2 and watch a recorded or downloaded 3rd at the moment and you don't really need a large hard drive now as it's all on box sets of catch up. As long as it's the same price then great but I don't think it's worth any extra money. Sky recently did a Netflix and put a whole series up at once it clearly sets Netflix and Amazon as a rival.
The fourth channel doesn't have to be prerecorded or downloaded. It can be live tv so theoretically, you're watching four channels at once. Bit ott imo
nah you can blame the bbc for that, ive never paid a tv licence either, told many a tv license guy to **** off and come back with a warrant, never been fined and they tend not to come back
