4) I actually like physical media.
This. I'm so happy with my F:NV CE :fallout:
Steam used to be a lot buggier than it is now, though. And as much as I hated to use it back when it came out, I will never forgive Valve for not releasing HL2 in physical format in stores here in Europe on the day of its release. I bought it through Steam and therefore don't have a hardcopy version of it, just the "Silver Pack" or whatever it was called, digitally, on Steam.
But still, in all fairness, a lot of their features nowadays are pretty cool.
