PlayStation Vita offers on-the-go gaming either solo or against others through WiFi or 3G, but there were recent reports that the machine would only support one PSN account. That's not quite true, according to a Sony spokesperson talking to Wired.com.
Each PSN account is bound to your Vita memory card, so if you want a second PSN account, you'll need a separate memory card. Sony's Crystal Mackenzie explained it this way:
Your PSN ID is bonded to your memory card and your memory card is bonded to your Vita. So if you wanted to change different PSN users but use the same memory card, you would need to go factory reset. You can also use them both on the same PSN account as well.
If you have multiple PSN accounts — whether from different regions or for different purposes — you'll need a separate PlayStation Vita memory card.
What do you make of all this?
