PSVita supports multiple PSN Accounts per system, but only if you have multiple memory cards.

So for every PSN account you have, you have to buy an overpriced SD card? Nice.

Still, with a portable device that really should be used by a single person, I don't see why this matters. I know I'd end up buying multiple for my kids if I had to buy one.

Reason why we have two DSi, they are personal use items. Not like consoles.

That or you can let a family member use your device without worry of them accessing your PSN account. Just pull out the memory card. 

No accidental purchases by my daughter when he gets a hold of this.

As for people whining about buying multiple memory cards for multiple accounts. 

 

You whine when you think you can only have (1) account max without needing to factory restore.

Now you whine when you learn that you have the possibility for multiple accounts without needing to factory restore.
