My only quibble with that list would be counting the East & West feeds as unique HD channels. If they are like their SD counterparts, then they are identical programming just 3 hours apart in the schedule... so while it would be nice to have Cinemax/HBO/Sho/Starz East and West... I would rather have just one feed of those and 4 other unique HD channels when it comes to efficient use of bandwidth.
Whenever we get caught up and have "spare" bandwidth, then I say go for the East/West feeds so folks have convenience for their timezone... but especially with DVRs we can timeshift on our own anyway... so lets have the unique channels Dish doesn't have before we go to the East/West ones.
So that, in my opinion, knocks that 23 channel list down to 19 channels... which is still a good list since there are some in there not yet on either Dish or DirecTV.
