My TV time has suffered due to my internet "surfing." I'd be surprised if I watched 10hours of TV/week. Usually it's under 5 hours/week, if that. I've listened to more radio in the car by each Wednesday than that! The rest is either spent with computers (which I do for a living), listening to audio, and maybe some mild human-to-human interaction to round out the week.
Are you spending your time at the computer instead
of listening to your system? Is your hobby leaning more and more towards internet sites and discussion groups on things hi-fi or are you still listening to as much recorded music as before? Do you do both at the same time, and if yes, do you think that it is a good thing to have a mega dollar system's sound "filtered" through a video display screen.
