You know... this topic has me thinking. When are we going to get to the days, where we can use 1 video game system on 4 different TV's in the house, without moving the game system. For example, let's say you had 1 Xbox 360, 1 Playstation 3, 1 Direct TV HDTV Tivo box, etc, etc. Why can't you have all those items connected to a single location in your home, and then be able to enjoy any of them in any of the rooms with the TV's?
I actually have three Xbox 360 systems right now, and two PS3 systems because of this very reason. I have a 360 and PS3 in my theater room, I have a 360 and PS3 in my living room, and a 360 in my home office/computer room. I have 3 total HDTV's, and a 360 is hooked up to every one of them. I don't use the systems at the same time, I just have seperate systems in each room to make it easy and simple. Before, I would have a component cable and power brick in each room, and just move the 360 from room to room to room, but that get's kinda old real quick. Especially trying to move a PS3 from room to room (heavy). I was able to get some extra 360's off Craigslist real cheap, and scored a second PS3 on a really good deal. (I'm not even close to being wealthy)
A big part of the reason I have two PS3's, is just because they are the cheapest Blu Ray player, and I really need to have a Blu Ray player in each of those rooms.
