No, xbox users cannot play against ps3 users.
No. A PS3 and a computer can be ran at the same time. A internet wireless network box is able to send a signal to multiple devices.
Do you mean can you send them a PS3 and they send you one. No They charge you to repair a broken PS3 if you send it in and sometimes they send you a replacement newer model
no
There is no way. PS3 users play on "PlayStation Network". XBox users play on "XBox Live".
PS3 can not play computer games so just download them on the computer
If you have an HDMI cable you can connect them but you won't be able to display the PS3 on the computer.
It all depends on your opinon but... PS3 has free internet, while xbox you have to pay for live Xbox (i think its only xbox only) you can send voice messages their pretty much the same, and all the big games like MW2 and Bad company release on PS3 and Xbox, but Halo is Xbox only and killzone is PS3 only
go to users in ur ps3 menus. it is the 1st drop down menu. you need 2 users and click the opposite one that your on.

Nope, the PS3 Network is completely free.
