As I am frequently moaning about the queues for computer use in our house I am sure it will come as no surprise that we are considering getting a second computer. 

I have several concerns etc that I'd appreciate some advice on.


I have several concerns etc that I'd appreciate some advice on.
- If i have two computers, I believe they can be connected together so that files can be accessed off both computers etc. If this is so, how are they connected. (they will be in seperate rooms one upstairs and the other in the room below).
- If I have two computers do I need a norton antivirus contract for each of them?
- Would I need two printers?
- Could one computer be XP and the other be Vista?
