XBOX Live.
The Main difference with Playstation Network or PSN over Xbox Live is that the PSN is free. PSN Plus at the same rate as Xbox Live has free games, discounts on others, online storage of your game saves, and automatic software updates to games and the console
It's actually known as a PSN ID. http://www.us.playstation.com/PSN/mediago
No. Xbox Live Gold is more secure than PSN and the Xbox is superior anyway. I disagree. Sure someone did hack PSN but someone hacked Xbox LIVE too. For game play PS3 is AWESOME. For graphics PS3 is AWESOME. For originality I give it a 8/10 because it takes some Xbox360 titles. For it's life line i give it a 10/10 because of the PS2 and PS1. Also, PS3 wont get a "Red Ring of Death" or anything like that. It will begin to make a really loud noise from its fans and that's when you shut it off.
You can't. PSN stands for PlayStation Network. You can't connect a DS to PSN.
WHAT DOES PSN STAND FOR OR MEAN
by PSN you need a account to PSN
The PSP-3000 can access the PSN, yes.
XBOX360
i have a question is the xbox360 elite the same as an xbox360 pro
No, PSN is free and there is no indication that is going to change.
Yes, there is a PSN link on the Vita's LiveArea.
The password is whatever you set it as when you registered your PSN account.
