When it appears it will almost certainly not be free, using the RVU in a Samsung TV is $6 so I expect the PS3 will be the same charge.
I believe you, but if that is the case I don't see the point of offering it for PS3 at all. First of all, it just seems wrong that they would charge me an additional fee to use hardware that they have nothing to do with. Can you imagine if Netflix tried to charge an additional $6 fee for each computer and streaming device you use it on even though they don't manufacture any of them?
Secondly, if it is the same price as the actual Client hardware why would anyone want it? I can somewhat see the point on a RVU Samsung TV because that uses a standard TV remote and doesn't have all the bootup time.
I cannot imagine a scenario where the PS3 isn't much clunkier than a real Client. I have the Logitech PS3 adapter so I am able to use my Harmony remote for Blu-ray and streaming services. That wouldn't be a huge issue for me but I can't imagine everyday channel surfing with a PS3 controller. Also the PS3 has to bootup and connect to PSN each time you turn it on. Then you would have to scroll over to video and then scroll the the video apps till you get to Directv each time you want to use it.
I'm not even sure free would be worth it compared to the normal $6 unit. I would at least give it a shot if it were free though. If it is the same price I won't even bother.
