technically less than 24 hours if you add the fact of time difference
I'm getting the show on Amazon so I can stream it wherever I want to watch it. I would get it on the PS3 but that would restrict me to having to sit in my living room to watch it. Sometimes that isn't an option.
There is a slight possibility that Syfy.com will have the show on their own site as well to promote it to people without cable etc. Most networks do this nowadays but I cant confirm whether or not they will.
