If I ignored any, I'll go back and look for sure and just PM you the responses if you like?
As to your second point, your webcam will only be accessed through your firewall. No ones going to break through a properly setup firewall, period. Mistakes happen because people are idiots. They are clicking links they should not be, accepting things from people they should not be, and on public wifi with limited to no firewall on a daily basis. You make it sound as if being hacked is pure luck of the draw, when I assure you that's not the case. Seeing as how this is what I (use to .. retired now) do for a living, I'm pretty damn sure I'm correct on the matter.
The third point is funny. If you would please take a glance at my Raptor, you'll see I'm a PC gamer. I've got thousands of hours into MMO's, many of which I doubt you've even heard of from Korea. My 360 is mainly my son's machine, as you can see from the games played. I play Fifa, and some RPG's on the thing.. that's about it.
I defended Microsoft's decision so heavily because it's my world.. PC. I've said it before, and I guess I need to say it again and again, but the digital transition in the PC world has been nothing short of amazing. It literally saved PC gaming, completely. Without digital, we would not be having the sort of discussion we are having right now, since PC gaming would be dead and gone or at most a shadow of its former self. Absolutely no one gave Microsoft that chance to see if they could pull it off, just like no one gave Steam that chance either. It's all guess work at this point, but I was, and still am, disappointed by gamers lack of patience to see what develops. If Microsoft flopped on their face, that was fine.. we had the PS4. If they did not, it would have been absolutely huge for gamers in general because Sony would have had to follow suit.
