Away from the 'no one box fits all' comments.
One thing I've noticed over the years is how much better the quality of the video/audio streams really are these days. I've used many different places to stream from, and it seems like it just gets better and better.
Currently I use iTunes, Hulu Plus, Netflix, Amazon Prime (yeah, signed up yesterday f/30 day free trial) and Vudu on a fairly regular basis, and some network specific sites on more rare occasions. Between the AppleTV(3), and the Sony 3D Blu-Ray player I have almost all covered.
Network specific shows unavailable on the subscription services are a bit of a PITA to use since there aren't any devices that cover even the majority of them. In my case, I use my MacBook Pro w/Retina to mirror to the AppleTV. While that isn't the most convenient way to do things, it does work very well. Because it works so well, I've eliminated the need for a DLNA server.
The only thing a DLNA server would offer is the ability to have more than one TV streaming at a time, but that isn't an issue here as my son finds more than enough to watch with the Hopper he has.
One thing that will be nice is being able to reduce my subscription level on Dish to a lower level and just keep HBO/Sho for boxing and original series. That will save some money, though with the streaming subs cost not as much as I would like.
