Heh...
I was an early Tivo adopter with what's now referred to as a Series 1 machine, it only came with 20Gb of storage.
This was back when you could get lifetime subscriptions for a flat $250 fee.
I bought it around 2000-2001, so it's close to 10 years old.
When I signed up for the lifetime guide option, ISTR subscriptions were $8/mo.
I figured I'd get my money's worth on the subscription if it lasted 3 years.
The Tivo is still running, on it's 3rd set of hard disks, and I still get guide updates without the monthly fee.
I only get basic cable, and it's still available in analog format.
I don't know which will last longer. Analog cable, or the Tivo.
Whichever one goes first will effectively make my Tivo useless, but I won't be too disappointed.
I believe I got my money's worth.
I also have an extensive MythTV setup with 2 analog and 3 digital tuners, with one dedicated for OTA.
It's not like I won't have anything to watch when the Tivo becomes useless.
