Not while there's BitTorrent!
I missed King of the Hill and The Simpsons this past Sunday night.
Monday morning, I found the them via a BitTorrent tracker and less than an hour later, there they were on the Desktop of the Mac.
I watched them, and then trashed them. No need to clutter the hard drive with ephemera.
As opposed to "The IT Crowd" and the as yet unaired in the U.S. episodes of Doctor Who.
However, viewing TV episodes on the computer is not the optimum viewing experience.
In a year or so, I think I'll start looking on eBay for used first generation Apple TV units. I should be able to afford one by then. Along with 30 feet of ethernet cable to hook it up to the computer.
