Congratulations! We took the plunge and cut the cable a couple months ago. Honestly, between Amazon, Netflix, and OTA content, I haven't even missed it. Although I have noticed the extra hundred bucks in my pocket.
If you're looking for a way to record shows from over the air, I've had great luck with MythTV -- it's a free software package that runs under Linux. I was previously using it to record cable television, and I just switched the configuration to record off of an indoor HDTV antenna instead.
