So what is normally the option on a ds?

Hey check it out! Now you can lock your save file information to a game using the specific memory card! No more save slots in games for your friends to overwrite accidentally!

I was giving a viable answer to your original question. Not necessarily what happens with other devices. 

The only device I ever allow anyone on is pretty much Wii and PS3. Wii due to the fact that it is really multiplayer games (Mario Kart and Super Smash Bros) that really don't bother me, and ps3 because other people can log into whatever account they have. 

The only way I would share the Vita, is if someone actually had a memory card, which they won't.... and no way am I going to buy two memory cards.

I come back from vacation and this is the first news on any video game system I'm reading on and I just have to say:

Kylie you have a ps3 so share it with your second account and voila.

See this is the problem.
Playstation fans seem to be always strapped for cash whereas xbox'ers have a million games, 5 systems, and lots of cash on hand.
Sony needs to work on getting the upper-middle class demographic. :D

1) I don't think I was stating any game console's solution is better than the other.

2) My point was just to help your lack of reading comprehension.

3) DS majority of games with saves on the game (inlcuding multiple) is by far the better solution than having to purchase an EXTRA memory card that can cost more than the games being saved on it as well as having to have one per user.

However, I still fall back to the idea that in reality the PSN account thing isn't a biggie as each person should have their own Vita... all I think is crazy is the overpriced and forced Sony branded SD cards.

This brings exactly the same problems as the "format to factory settings" thing with the only difference being that you don't have to format to factory settings to switch accounts :S. I still won't be able to use any DLC I get with a US account on my Argentinian account, won't be able to play any games I buy with a US account with my Argentinian account, etc.

Here's hoping Sony creates a PS Store in my country by the time the Vita is released.

I think this is the only thing that bothers me about the Vita. Even the "high" prices that everyone complains about didn't bother me, even though the WiFi only version will most probably be 500+ US Dollars here instead of just 249 like the US... and even though all memory card prices will be at least 2x the prices of the US, it was still fine for me :S

I guess I'll have no choice but to play US content in a US account.

I'll have to buy all my games phisically though, since buying digital will oblige me to play in my US account and I don't want to do that >_>. I wish it was like on PS3...

That's why I'm glad I have multiple accounts on my cell phone. I don't want anybody using my phone to call other people--they have their own....no. That's not......uh. That's why I'm glad I have multiple accounts on my 3DS! I don't want anybody messing up my save data....no. Can't do it there, either. Fuck.

Okay. Sony is in trouble. They need the Vita to be a grand slam and the negativity around it is deafening. And why? Half the people complaining aren't buying a Vita anyway. Of the half that will buy a Vita, half of them won't make a second account if they could (like I didn't with my two PSP's). Of the half that do, they'll soon realize that a 32 MB memory card doesn't really hold a lot of portable HD content. They'll likely buy physical copies of their foreign games (because we all LOVE playing foreign games we don't understand, right?

It isn't reading comprehension at fault. I'm just bypassing the argument by saying, "where else do you even get the option".

Nowhere. So why are people complaining? Think of it this way. The identity of your system is tied to your mem card. You pull that out, and it's a blank machine. That's fucking cool if you ask me. Nowhere else do you get that option.

And the complaint about having to buy two copies of a game?

You have a ps3 with mutiple accounts. You download on one, share to the other, download both accounts to different mem cards. No buying two versions! Then you have the US/Japan, or EU/Japan, US/EU etc etc.

And please, people complained when they were limited to how many copies of a game they could share. Seriously. I can't permanetly give copies of my downloaded games to my friends for free. Fuck Sony!

I think the only real point here is that the cards are expensive. 50$ is quite a bit. But youknow what, I'm not uncormfortable with my friends playing with my portables. And if I was, I'd probably already be of the mindset that my hangups cost me money in hand sanitizer, plastic wrap for my couch for when friends come over, buying a second bottle of coke in case a friend wants a sip of mine. :D

Actually, quite a few places.

1) Any Android device. I can have and do have multiple google accounts including one my wife and I share for Google Music so we can share all the music we purchase. This would include phones, tablets, google tv, etc. (I don't own iOS or WM, but I'd bet at least WM does this as well)

2) PS3 and 360. You can have any number of PSN/Live accounts and utilize them individually on the same machine without anything extra.

3) All Nintendo handhelds based on the game itself. While games like Pokemon force one save at a time, the greater majority do not and multiple people can all share the same system/game with different game saves without any extra cost. Hell, quite a few games allow you to play multiplayer with only one copy of the game with numerous other same system owners. Now here the console is tied to the store and digital purchases which in itself is a poorer solution than having a PSN/Live account, but, that's a different argument.

4) Any PC/Mac/computer. all of these allow you to create any number of profiles with fully different settings and even applications all from the same hardware without any extra cost.

Fact is, its a damn shame how Sony is forcing this limitation on its users and I'm 100% positive its based solely on increasing their bottom line, not consumer experience or technical limitations.

They should have followed their PS3 approach with a limited in device memory (<16GB is cheap) that allowed n number of PSN accounts and then utilize a normal SD card slot for memory expansion. This would have allowed them the security model (as that would be on the internal memory) as well as the extra storage needed for bigger media or simply more of it. I am sure they thought of this solution.
