I have had the cable tv dvr's for the past 4-5 years. I have never owned a Tivo until now. I bought a Series 3 because of the functionality and better interface. The only thing cable tv dvr's beat the Tivo hands down is the ability to pause live tv for 1 hour. I love everything about the Tivo but being able to pause from 30 minutes to 1 hours is big to me.
