I don't know what the hell just happened to my PC and phone but VGChartz is taking forever to load on my PC and won't let me post on my phone (until just now).
Anyway, I was wrong.
I went to Netflix.com and deactivated Netflix on my PS3 and 360. I then went to the PS3 and tried to use Netflix. It asked for my email address and password (for identity theft purposes, I assume). I was back to watching movies in about ten seconds.
Then, I went to my 360 to fire up Netflix. It gave me a seven digit code that I had to type in at www.netflix.com/activate. I typed in the code and was back to watching movies in about 13 seconds.
So yeah. I was wrong. I assume the Netflix registration process changed for the PS3 when they went from disc based to disc free (or I'm just getting senile in my old age). Still, both methods were quick and painless and didn't take a minute between firing up the app and getting the service. I don't see how this could possibly be a problem for anybody that wanted to use Netflix on either device. In fact, I don't even see it being a factor for anybody that only owns one device.
Also, beware of my wrath. I shall unleash the Weather Dominator (I took it from Cobra after they were defeated by G.I. Joe) on this world in the very near future. You shall all learn to fear the name of D21!!
