The Cable Man Cometh

Today, I got High-Definition cable. This is after my Christmas present to myself of a 43-inch high-def-capable Samsung DLP projection TV. I just have to say that HD is amazing -- when the cable guy turned on ESPN-D to an NBA game, I was amazed.

That said, why is it that the cable company asks for a four-hour window when they know darn well they'll show up in the last 15 mintues?
