Completely agree!
I LOVE HD! But, there's still too much out there that's SD for me to completely give it up. Over time, I think that will gradually change. But, on top of that I would still need to get locals via OTA (which is not possible for some of my locals). On top of that, a great deal of the stuff I've seen on Voom just doesn't do anything for me.
I want (pretty much in this order)
Locals in HD
Premiums in HD
Sports in HD
Other stuff in HD
The ONLY provider that has been able to deliver on that is Adelphia. E* couldn't, D* can't. Voom cant. Obviously, that's not the case for everyone. Lots of other cable providers are more capable or less capable than mine, so YMMV. Over time, however, I really believe cable will end up killing both E* and D*. E* first, and I think it's because they just aren't keeping up in any single area.
