I like the HD programming as most sports and nature shows look really good in HD. Other than that, it's a bit of mixed bag for me. Many prime time programs are available in HD, and they do look better in most cases, but not the night and day difference I experience with sports and nature shows. For me, it was only $5 difference in service (Comcrap) so it's been definitely worth it. We'll see if things change when I switch over to FiOS TV in the near future.
